[Work In Progress] Parametric OpenSCAD calendar (lemmings.world)

So, I'm making a fully customizable calendar in OpenSCAD with the following features:

  • correct columns for every date - uses an algorithm to calculate the correct day of the week for any date, you just change the year and the calendar is correct
  • fully translatable
  • supports custom holidays
  • supports both MMU/AMS and single extruder (with the help of M600 or similar)

Planned features:

  • configurable holes for magnets or holes for hanging the calendar
  • configurable first day of the week

I can share the SCAD file, though beware it's a work in progress and I haven't test printed it yet.

This looks great! I love OpenSCAD, and this is a pretty feature-rich usage.

Are you planning to print it for regular use as a calendar, or is there another use case you had in mind?

[–] rikudou@lemmings.world 6 points 4 months ago (1 children)

Just a calendar to hang on the fridge. To be fair, my main reason for doing it was to see if it's possible. Do you have any other use cases in mind?

[–] owenfromcanada@lemmy.world 2 points 4 months ago

I was mainly curious as to whether this was mostly a fun exercise, or if there were a practical advantage to having the calendar printed in 3D. Cool either way.

I do most of my cad stuff on openscad and I will say that is impressive!

Particularly since the openscad language is purely functional and side effect free.

Thank you!

Looks good. Does it do Easter calculation?

[–] rikudou@lemmings.world 3 points 4 months ago (1 children)

It doesn't currently, don't know if it's possible like that. But you can input your own holidays, which is what I did for the screenshots.

I did that Easter calculation for a spreadsheet calender once. Calculating it was easy, getting it into the calendar display was a pain...

What algorithm did you use?

[–] Treczoks@lemmy.world 2 points 4 months ago

Sorry, don't remember, that was somewhere in the 90s or 00s.
