3D Printed DC Motor/Generator - Extended Armature

This is an extended shaft version for https://www.thingiverse.com/thing:4704606/

I extended the shaft to put props on it. Just add a 5.2mm hole on whatever you'd like to press it on.

The source file I made is here: https://cad.onshape.com/documents/caf6982cda28b370b65b399c/w/c83838973737c9a3a6de4a5b/e/1d199068ac6d359b44814c19

Be sure to print in something like PETG with supports so it stays nice and straight. Straightness is very important for good brush contact and operation.
