Universal Syringe Pump V3b

A syringe pump that will fit most syringes found in the lab(tested with a range of Norm-Jects from 1mL to 30mL, also Hamilton glass syringes) and can push or pull with no change in configuration.
The mounting rail is compatible with Lego Technic standards.

No supports needed. It is advisable to print the motor mount in PETG as PLA can warp if the motor gets too hot. PLA works fine under normal loads.

Controlling electronics not included. You will need to put together some kind of controller to drive the stepper motor as required.

Hardware (WIP):
NEMA 17 stepper
Shaft coupler
T8 leadscrew or M8 threaded rod and nut
608ZZ bearing
M8 smooth rods x2
M3, M4, M6 and M8 hardware.
