Keyboard wrist rest

thingiverse

Full size keyboard wrist rest (380mm). It is meant to be printed vertically and in TPU (ideally a85). I found that 2 walls and 5% gyroid infill worked really well and NO top or bottom surfaces. This will make is flex more evenly and with the gyroid infill looks really nice. I found orienting the wrist rest like in the picture gave really good support and even squish. If your keyboard is further away from you and you use rest your hands down (rather than press them down) try a lower infill. Print a small piece, at least as big as your wrist, to test out the infill. You will likely want to slow down the print as the print gets taller. At 60% I slowed the speed to 90% and at 80% complete I slowed it to 70%. By the end I needed to be at 50% speed. I didn't need a brim but you know your printer best. I glued a thin sheet of foam (dollar store) over the top (using foam glue) for comfort but it will work fine without. The foam makes the slight layer shifts (at the high end) unnoticeable. I only put glue on the under side and at the bend so as not to stiffen up the foam (although proper foam glue is almost unnoticeable).
