Minimal Arduino Useless Machine M3

Just LOVE the original thing: https://www.thingiverse.com/thing:4561617

But i´m usually into threaded inserts, but only when i need them.

For this usage i don´t think inserts is needed so i remade the "body" to use M3 bolts just threaded by themself, and a version where you use the screws that come with seratain servos.
