Your current plan is solid. Print the plate with fdm, though it can't be too thin. There are a few designs on thingiverse and etc. to get an idea on how thick.

Ergonomic, split and other weird keyboards
Rules
Keep it ergo
Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)
i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²
¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

Hmm what's the rationale to print the plate with FDM? Are SLA plates brittle or inflexible? (if printed with ABS)? I don't have much experience with SLA. And good point, I'll check Thingiverse for the thickness.
It's just more due to the size and it being a mostly flat print makes it ideal for fdm.
Ah that's true. I got the SLA printer's build volume and indeed it can't fit a whole half of the split kb in any way.
The main problem with SLA is the material and size. I don't think SLA can print ABS?
I think this SLA printer can print ABS. Or at least I'm told the default resin is ABS-like. Probably not as durable I'm guessing.
For my board, I printed keycaps, plate and case all with FDM in PLA.
Dude, what settings did you use to print those? Did you do any post processing? They all look amazing
No post processing on any of this. The case and plate were just with my standard printer settings, nothing special. For the keycaps, I printed them at an 80° angle so the stems would be stronger and used organic supports. 0.1mm layer height and oriented so the layer lines are along the finger travel direction so you don't notice the layer lines in use very much
Do I see fuzzy skin on the plate at least?
It isn't fuzzy skin as set in the slicer, but it is texture imparted on the switch plate by using a textured PEI build plate.
Can you share the files for your case? I'm wanting to make the same (Hillside 40, no?), but can only find files for a 46, and am hoping to avoid the learning curve needed for 3d modeling. Thanks.
This is actually my fork of the Hillside with enough PCB changes that the case won't directly work with the original hillside unfortunately. Here's my repo: https://github.com/wannabecoffeenerd/hillside
I see. Thanks for sharing. I'll check it out.
Wow, that looks gorgeous!!
For wrist rest, you can stick a piece of TU leather to cover the printed surface, so it will look nice, be clean and comfortable. Not sure if TPU is sufficiently soft if you want a soft wrist rest, you would probably need something like silicone.
Nice idea! Do you mean on top of the switch plate? I'm still brainstorming the design, but it will have a removable layer on top of the plate to hide the switches' legs (I don't like that "naked" feel) & keep some dust from falling inside the kb.
I just did it for the wrist rest, as that is the part your wrist will touch regularly. It is too much work to cut many holes if you want to cover the plate, and I don't think it will be much cleaner comparing with bare printed surface. You still need regular cleaning.
