Hi All,

I'm planning to print a plate & case for a handwired 46-key split kb. I have access to both SLA & FDM printers at a fab lab, so wondering which printer tech would be best to print various parts such as keycaps, plate, case etc. Function's more important than looks for me.

I'm allowed to use PLA or TPU for the FDM, and the default resin (ABS-like?) for SLA.

I'm thinking:

Keycaps: SLA (I want really thin keycaps)
Plate: ?? (not sure what's better for a thin & durable plate that allows a bit of flex when typing)
Case: FDM (Due to costs, and easy to embed screws & magnets)
Wrist rest (if any): FDM? Would TPU wrist rest be clean or comfortable?
Gaskets, extra layers (if any): FDM (cuz TPU)

What do you think?

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.

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
