As far as I know (I have never 3D printed), yes. I vaguely remember a guy who tows around a 3D printer on his bike into parks, and prints parts for people. It wouldn’t be instant(I’m guessing they tell the person to come back later), but it is possible. I’ll try to find the video haha.

Keeping in mind I’ve never 3D printed, here are some sites that look promising.

https://www.traceparts.com/en https://grabcad.com/library

Also, I’ve seen tutorials for 3D printing on Instructables, and people sometimes give download files in the instructions.

They go off of who volunteers. For example, if a person who specializes in fixing stand mixers volunteers, that will be one of the tables people can visit. That repair person brings the parts (for example, there are a few parts in stand mixers that tend to break, so the repair person would know to bring fixes for those). I have also heard of repair cafe's elsewhere even bringing in 3D printers to help with part replacement.

Here is the text from a recent one in my town:

Items that are accepted at Repair Café events:

  • Electronics such as gaming consoles, CD player, DVD player, camera, adaptor cord, etc.
  • Small appliances such as toasters, coffee makers, lamps, waffle makers...you get the idea!
  • Smaller pieces of furniture such as small wooden furniture pieces, a clock, or a plastic item that needs some crazy glue.
  • Toys! Whether it needs glue or some wire soldering, we can try to repair it!
  • Clothing or housewares (clean please!) that need mending. Full alterations will not be done.

Items not allowed:

  • Microwaves
 

RIGHT TO REPAIR

A big fight is happening world-wide to push governments to ensure people can repair the products they own.

“The right to repair refers to proposed government legislation to forbid manufacturers from imposing barriers that deny consumers the ability to repair and modify their own consumer products.” | Wikipedia

This is happening because of:

  • Planned Obsolescence: companies are purposely building their products to break faster, so you have to pay to replace them sooner.
  • Unfixable Products: some products will have their components soldered, glued, or riveted, to stop people from being able to repair.
  • Brand-Specific Parts: These parts may cost more than buying a new product. As well as that, some companies refuse to let independent repair technicians purchase their parts to try and force costumers to only use the product company for repairs.
  • Restrictive Programing. For these, the programs refuse to let you fix your own products (a large example of this happens to farm equipment, where farmers have to hack their own equipment if they want to repair on their own).

REPAIR CAFES

Repair cafes are typically community-run events where volunteers gather to fix the broken items of strangers for free. My town started doing it a long time ago, and it was so popular that it now happens several times a year.

People bring in stand mixers, vacuums, computers, items that need sewing repairs, and more. Often, the person is very willing to explain the repairs as they do them.

In other places, repair cafes have become more permanent. For example, in Austria, the government started paying those who repair.

Repair cafes not only save people money, but they also can greatly reduce the amount of waste produced by saving those repaired items from the landfill.

For food forests, you do what you can to use edible plant life to mimic the ecosystems of a wild forest.

“A food forest, also called a forest garden, is a diverse planting of edible plants that attempts to mimic the ecosystems and patterns found in nature.” | Project Food Forest

If done right, this system will…

  • Promote a healthy soil microbiome
  • Increase carbon-capture (no-till)
  • Prevent erosion
  • Retain water

And more.

Personally, I suggest using as many perennials to your area as you can so you don't have to replant everything every year.

Here are some perennial examples that are for my specific area:

(⚠ means you may want to container garden them to prevent spread)

  • 🥬Lovage (celery alternative)
  • 🥗 Bloody Dock (chard alternative)
  • 🥗 Good King Henry (spinach alternative)
  • 🥔 Jerusalem Artichoke (root vegetable)
  • 🥗 Sea Kale
  • 🧅 Chives ⚠
  • 🥝Hardi-Kiwi
  • 🍓Wild strawberries
  • Raspberries ⚠
  • Wild blueberries
  • Red or Black Currants
  • Haskap/Honeyberries
  • 🍇Valiant or Bluebell Grapes
  • Rhubarb
  • Saskatoons
  • Pembina Plums
  • 🍒Evans (sour) cherries
  • Manchurian Apricots
  • 🍎 Hardi-Mac Apples

I haven't tried petting a bumblebee, but I believe you! They are the gentle giants of the bee world

 

Years ago, I took an online course on mountains, and one fact that stuck with me from it was about how people in the USA accidentally polluted the water in New York City by cutting down trees.

It was the 1800s, and the trees in the Catskill Mountains were cut down to accommodate growing populations, and as a result, the water quality for New Yorkers deteriorated rapidly. Yes, the agriculture pollution and sewage did play a part, but the trees were decided to be such a big problem, that they decided something had to be done.

So, they purchased land, and planted 18000 trees to restore the natural ecosystem.

How does this water-cleaning work? With watersheds.

“Watershed: an area of high ground from which water flows down to a river” | Cambridge Dictionary

Imagine it is raining in a forest. Droplets hit the ground, and —thanks to the vegetation which slows runoff — it is absorbed into the soil like a sponge. As the water moves through the soil, microbes are actively removing harmful pollutants, silt is filtered, and plants removing fertilizers.

Some of the water will end up in our lakes and streams, but will be much cleaner than when it started.

"The ability of forests to aid in the filtration of water doesn’t only provide benefits to our health and the health of an ecosystem, but also to our pocketbooks. Forest cover has been directly linked to drinking water treatment costs, so the more forest in a source water watershed, the lower the cost to treat that water. Forests provide these benefits by filtering sediments and other pollutants from the water in the soil before it reaches a water source, such as a stream, lake or river." | American Forests

Since this intake and outtake of water is gradual, removal of these forests can even to lead to a higher chance of both droughts and floods.

Have you ever wondered why so many large chain stores have two sets of doors? No, it is not just to store shopping carts.

Where I live, any home that is around 100 years old (that hasn't seen any renovations) will very likely have two front doors. Putting it simply, you open one door, step into a small space, and there will be another door in front of you.

(Image Sources: Image 1 | Image 2)

The space goes by many names, including: arctic entry, mud room, breeze room, vestibule, airlock, foyer, and more. For sake of simplicity, I am going to call them "entry vestibules."

Entry vestibules create a buffer between the outside and the inside of the building, preventing drafts. This can help greatly with temperature regulation in both the winter cold and summer heat. I can't find number details on energy saving, but the fact that large chains still build them may hint of their importance for money-saving.

In homes, this space also typically serves as the mud room ( a place for shoes and jackets).

In the name of "first impressions," and open concept designs, vestibules are often the first thing to go during renovations, and I think that's a real shame.

 

Have you heard of the beautiful living root bridges in Meghalaya, India? Their construction is a lesson in patience as the roots are gradually encouraged to grow in the supportive shape. They need regular care, but grow stronger with age.

“Once a bamboo structure has been stretched across the river, the roots of the tree, usually the rubber tree (Ficus elastica), are teased and manipulated to become entwined with the bamboo until it becomes a strong mesh. The roots are allowed to grow gradually and strengthen over time. In the initial stages, only about 15-20 people can cross the bridge in a day. Much later, it can be as many as 50 or more, although it can take up to two decades for a living roots bridge to be finished.” | The Guardian

Once done, the bridges can have a lifespan of several hundred years; far outliving the original creators of them.

It is unknown when this tradition started, but they were written about in 1844, so it would be far earlier than that.

I just thought people on here might find this tradition as fascinating as I do.

I edited it to add the video! Sorry about that! I posted it on my phone, and thought it worked, but it didn't.

[–] Blair@slrpnk.net 3 points 1 month ago (3 children)

That one photo isn't mine (image source link is below it) but I added it because it was exactly what I was talking about. That example would have been in the area of honeybee boxes(those are all honeybees), though they can travel around 1-6km from the hive. They will drink water for themselves, but also bring water back to the bee boxes for the other bees.

Random fact, though, don't be scared if this happens to you. Honeybees gathering water are not aggressive and will die if they sting you, so they will only sting if they see it as a last resort. For example, here are some photos of a honeybee I rescued from drowning. After she dried off, she flew away.

Ah! You're right, sorry! I posted it on mobile and thought it worked, but I was wrong. Thanks again!

It looks like you can! This is from the Farmers Almanac website, which has a tutorial

Thank you! That looks like a great system

 

If you want an easy way to help your local pollinators, then consider building a water station! Many plants and crops rely on pollinators, so the more you attract and help, the healthier your garden will be (for example: "“Bee pollination improves crop quality, shelf life and commercial value.”)

For a basic one, you will need:

  • Tray or dish
  • Rocks
  • Water

The tray or dish is to hold everything, and the rocks are to give the pollinators something safe to land on. Without the rocks, you will likely end up with drowned bees. Due to evaporation, you may have to fill the dish once or more a day.

HOWEVER, although that is the most common method, there is another one that I prefer that was taught to me by local beekeepers. They use a refilling dog bowl instead of a dish, so it doesn't have to be filled as often.

(Image Source)

While this was advice from beekeepers, the watering stations are not limited to honeybees; you may see all sorts of native pollinators visiting.

If you can't buy a refilling bowl, here is a tutorial on how to DIY one.

No matter what you choose, though, the pollinators will appreciate it! I do suggest putting the water in shade to limit possible algae growth.

 

A family in Wales is farming in the ocean. On suspended ropes, they farm seaweed, mussels, oysters, and scallops. This method is not just mutually beneficial for what they farm, but is also helps the ocean habitat.

There are no nets around the area, so wildlife is free to enter the area.

One major way this farming method helps is that it creates an exclusion zone to prevent fishermen from trawling it. This could have a direct positive impact on over-fishing by giving wildlife safe havens.

Brown believes a thriving ocean farming industry could provide solutions to the UK’s fish stock, which is in “a deeply troubling state” according to a report that found half of the key populations to be overfished. “It would create stepping stones where we have safe havens for fish and other organisms,” he adds.

 

"The rock powder, usually basalt, is often scavenged from local mines or quarries, where it exists as a waste by-product. ERW companies collect the rock powder, sometimes milling it further to reduce the grain size. Then they truck it to farms, where it is used in place of ag lime.

Studies show that volcanic rock dust can raise the pH of overworked soils, improving productivity." Modern Farmer

Have you heard of The Great Dust Bowl? It was a series of dust storms in the USA that were so intense, they killed crops, livestock, and people during the the great depression.

The situation was amplified by a drought, but the dust was also human caused.

“Following years of overcultivation and generally poor land management in the 1920s, the region—which receives an average rainfall of less than 20 inches (500 mm) in a typical year—suffered a severe drought in the early 1930s that lasted several years. The region’s exposed topsoil, robbed of the anchoring water-retaining roots of its native grasses, was carried off by heavy spring winds. ” Britannica

This dust storm was so thick that it blocked the sun.

“Dear Mr. Roosevelt, Darkness came when it hit us. Picture taken from water tower one hundred feet high. Yours Truly, Chas. P. Williams." An unknown author writes to Roosevelt

Under the hands of desperate farmers, grasslands turned to landscapes so lifeless and dangerous, that many people abandoned their dreams and left.

One of the practices that amplified this disaster (that is a current farming practice to this day) is rototilling. During this, you flip the soil over, which can make planting easier. This comes with many problems, including:

  • Destroying the soil microbiome. Healthy soil means healthy crops.
  • More weeds. As you flip your soil you are allowing dormant seeds a chance to thrive
  • Soil Compaction: As the soil gets more compact, it becomes harder for roots to work through it.
  • Washing or blowing away top soil. Top soil is where the heathiest soil is, and it can be washed away if left uncovered
  • Drying the soil. By leaving the soil exposed you are letting the sun bake out any moisture

Fixes:

  • Crop rotation. This is a pre-medieval technique where you rotate what crops you grow in what soil. This can add nutrients to the soil, avoid nutrient depletion, reduce diseases, and reduce pests.
  • Cover Crops. Never leave your soil bare. Cover crops can save your soil.
  • Water Catchments. These slow down the movement of water, encouraging the soil absorbing it. Examples: bunds or swales.
  • Alternative farming. Such as aquaponics or hydroponics.
  • Food forests. Instead of rows of monoculture, food forest combine several different types of plants in a way that mimics a forest.
  • Reducing food waste. To take pressure off food production. In Canada alone, $31 billion dollars worth of food waste is thrown out a year.
  • Mulch. Putting mulch down can protect your soil while also keeping down weeds.
  • Planting trees and bushes. Even if it is just on the outside perimeter of your crops, trees and bushes can help hold soil in place, reduce wind, and improve the general health of the area.

Did you know that you can grow your own bath sponges?

"Luffa is a genus of tropical and subtropical vines in the pumpkin, squash and gourd family.” Wikipedia

Luffa plants are from southeast Asia, and can be grown in places with a long warm summer. The fruit can take a long time to grow and toughen it’s inner fibers (about 150-200 days), but after that time, they are ready to become sponges.

Explaining it simply, you peel the skin, wash the insides, hang them to dry, then you are done.

“Getting all the seeds out can be a challenge, but the drier the sponges are, the easier the seeds will fall out. Save the best ones for next year. You can also cut open the sponges in any shape you want to remove seeds or make a loofah fiber mat.” luffa.info

When done, you can use the sponges for bathing, washing dishes, and even as industrial filters.
