No post processing on any of this. The case and plate were just with my standard printer settings, nothing special. For the keycaps, I printed them at an 80° angle so the stems would be stronger and used organic supports. 0.1mm layer height and oriented so the layer lines are along the finger travel direction so you don’t notice the layer lines in use very much

For my board, I printed keycaps, plate and case all with FDM in PLA.

Yeah, both valid points. I was asking about the firmware supporting an esp32 specifically for the wireless capabilities. And on terms of battery life, I went overboard and installed 3000mAh batteries in my keyboard that I can use to power the display 😂

Oh neat! QMK seems to be the most appropriate for trackpads. I was thinking of something that could be wireless which afaik QMK doesn’t support. And ZMK’s support for pointer devices is not great just yet.

This is super cool! Is the firmware flexible enough to support a similar ESP32 based chip? Something like this. That’ll then allow you to make the touchpad wireless over BLE and just stick it on any keyboard as long as you have a way to power it.
