This is a modular hobby servo Linear Actuator joint assembly. It is part of the Tiny_CNC_Collection of parts designed to facilitate entry into robot building fun!

All parts print without supports or post processing! Everything can be assembled with a screwdriver and single type of screw. See photos for assembly directions.

Specs: Repeatable no load motion control = +/- 0.076mm (.003”) up to 100g before position control affected. Travel limit is 80mm (3.14”).
