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.

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

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.

wondering if it is faster for you?

a soldering iron at 360 degree celcius

yes this is how I did it!
