I think i'm onto something here, but the design is... Awful. Yes, technically this device can press the glass plate (with the design) down onto the PCB blank carrier. But the whole concept with the four pillers is.. Eh. Alignment is a bitch, and it all binds a bit too much. But i think i can make this work. I tink it works a bit better when i make the base plates out of a more precise material instead of MDF. I guess this design requires some amount of precision. I might redo the design, but i also dont want to waste more time. I just need something to etch my own PCBs
