Description

By removing ALL fasteners and using a 100% snap-fit assembly, assembly time is cut down 6 fold! Hopefully this design will also be more accessible if you struggle to get the right parts for my projects. If you don’t want to use my new PCB design (which admittedly is a work in progress) refer to my previous design for electronics/wiring instructions.

If you do want to use the PCB, note that its still a work-in-progress. The design works although there is an issue with some holes being undersized. In theory the attached file is fixed but I’ve yet to test it myself to be 100% sure!
