Buttonplate for aliexpress 320mm wheel Porsche cup style

27-nov. 2021 - removed WIP status, since a couple of people have succesful build this project.
17.nov - updated "plate-body" and "back-body", corrected a hole and added some wire holes too.
Momentary removed the neopixel addon since dimension was wrong will update soon.

! Notice resin printers will not accept "plate-body" since its 2 3d parts exported as one.
I have added an alternative "separated" "plate-body" in two parts for those woh's printer wont accept the "plate-body" stl file.

This is still a work in process. If you print it, I would really apreciate feedback if something should be adjusted.

Complete buttonplate with gearshifters, fitted to work with an Aliexpress "OMP" replica wheel and a 70mm quickrelease.

Good soldering skills, because there are not much room for fitting wires and arduinoe with usb cable.

I dont have wiring schematics or arduino sketch, since im using simhub to control it.
