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?

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.

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
