About this 3D model

14.4 : 1 reduction ratio M5 nut fixture 0.8mm/turn (pitch) you will need an M5 hexagonal head screw, at least 70 mm long. since the control of the speed is very accurate the distances are arbitrary but the math needs to be done EDIT: - the the v2 files can be assembled with the parts that have not been updated to v2. - the gear profile has been changed to better fit the worm - the worm has been slimmed down for a better fit the cage has been slightly modified to fit the worm&gear changes - the design has been checked overall for a better fit.
