Description

This is my Prusa Spool Bot which makes a radio controlled robot out of a 2Kg filament spool!

Internals printed in Prusament Black PETG with the filament sections printed in material of your choice, I have gone with Prusament Orange PLA.

I used PrusaSlicer with optimized print settings at 0.25mm layer height. The only adjustmet is to set 3 perimeters instead of 2.

The code, wiring diagram, and BOM are available on my GitHub account here: https://github.com/mantisrobot/SPOOLBOT
