40% low profile keyboard?

I am a vim user (and use vim keybinding for web browsing), so I rarely need to use both my mouse and keyboard at the same time.

yeah, they are quite delicate. I wanted to use thicker ones but it is hard to get thick magnet wires. I never tried dropping them so idk, I guess making them less tensioned would help a bit

yes this is how I did it!

This looks pretty! Wondering where you guys get those fancy choc keycaps as well, I usually go to aliexpress (taobao in hk) and choc keycaps are much more expensive comparing to the normal kind of keycaps. I can usually get 60 normal keycaps for around $10 USD, but the price easily doubles for choc.

wondering if it is faster for you?

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.

The main problem with SLA is the material and size. I don’t think SLA can print ABS?

Not sure about others, I tried to sell me keyboard but without success, maybe split keyboards are a bit too niche and no one near me (HK) is interested. I just disassembled the keyboars to scrap the components for the next build, which is a bit sad considering a significant amount of time is spent on assembling it.
