Automatic syringe plunger for MG90S servo

Description

Syringe plunger that can be automated using a microcontroller and a servo. The plunger is designed to fit a 100 ml syringe. Travel distance of the plunger could be increased in another version. 

Printing

Can be printed with minimal supports (touching baseplate are the only ones necessary). For the bolts I've printed these at 75%.
