Full Build guide: https://www.youtube.com/watch?v=0jRsltIW8qM&lc=z235yfex0v3hzldc4acdp432jmqwfhyhzei1bhyiu0lw03c010c

Purchase links and schematics are in the YouTube video description. Be aware that this is a relative extensive project.

Print settings:
All parts are printed at 0.2mm layer height (except for IO shield)
3 walls and 35% infill for all.
Some files need to be printed using ABS or PETG to avoid melting.
IO shield is printed using 0.2mm Nozzle and 0.15 layer height with a filament swap in between.
