Here's the MW65 Lite Proto from MWStudios! It's a inexpensive gateway to a flexy keyboard, with a flex pcb and plate, south facing and via supported as well!
Got mine in a sandblasted acrylic case as it was a proto but retail units should be made out of Polycarbonate, you could say I have a 1:1 rare copy of the keeb! haha

Built with Jelly Blacks and PBT Dots, Tape, IXPE, No Foam, Cherry Clip-ins
Keycaps are TaiHao Camel and PBT 2048!
