ErgoDox Infinity full hand case extension

thingiverse

This print replaces two acrylic spacers for the ErgoDox Infinity to add built-in wrist rests to your keyboard. It is based on original case files available on the Input Club GitHub. This version features: - Full-hand extension/wrist rest that's built into the case. (The top surface aligns with the top of the acrylic.) - Improved I/O housing on the back of the case - Minimal additional hardware ## Instructions You will need to print: - 1x ergodox-case-R - 1x ergodox-case-L - 4x ergodox-case-foot You will also need: - 4x M3 screws with flat/countersunk head. Any length from 8mm-17 mm should work, but I built/tested with 14 mm. If you don't have screws, you can just glue the feet on. I printed in PLA at 0.2 mm layer height, but the specifics shouldn't matter. No supports are needed, but you might have to rotate parts to fit on your printbed. They do fit on the Prusa. After printing, you will need to completely unscrew your keyboard and remove two acrylic layers immediately under the metal plate. Replace these with new printed part and reassemble remaining layers. You can then add feet to bottom front of full hand extension. They attach with M3 screws, which are self-tapping into body (no nuts needed). Feet are designed to line up in height with bottom of keyboard, if keyboard has included black rubber feet attached. If they aren't the right height, you can chop off/extend non-countersunk side of foot or ask me and I can make a different size.
