After receiving the PCBs and 3D printed key caps from PCBWay, I assembled everything with the case plates I picked up last week for a first fit-check and sound-check.
I’m really happy with how everything fits, feels and sounds. Thanks to PCBWay for sponsoring the PCB and key cap production for this prototype.
The next step is soldering all the electronics and finishing the firmware. If all goes well I’ll post more pictures with RGB backlight in a few days.
The little holes are for the LEDs to shine through because I wasn’t sure how opaque the 3D printed material would be. Turns out that the holes are probably not needed.
My layout for v0.2 is here (I’m using the Colemak version): https://github.com/fxkuehl/qmk_firmware/blob/mantis-v0.2/keyboards/mantis/keymaps/default/keymap.c
