Overview:

A key component to a future project idea, this spring loaded graphite brush keeps electrical contact to rotating/moving conductors. This first prototype was mainly to test the concept and the resolution of my 3D printer to see if small brushes were feasible.

BOM:
-3D Printed housing and plunger
-Scrap copper wire
-Copper tape
-Spring from old mechanical pencil
-Graphite from old #2 pencil
