Lead screw driver with bearing and technic gear
thingiverse
As part of a larger project, I have developed this mechanism for driving a TR8x8 leadscrew with a Lego motor. This would be a valuable component in something like a linear actuator. This creation is a remix of my previous work on https://www.thingiverse.com/thing:3939083 and Corona688's excellent design: https://www.thingiverse.com/thing:3419926 for the lead screw interface. It connects with a Lego motor such as the EV3 medium servo motor 45503 or LEGO Functions Power Functions M-Motor 8883 via an 8-tooth gear. I have used 6mm balls, similar to those found in Airsoft.
