Try press fit..
Converting Vertical Motion into Horizontal:
Shout out to B-RYCE:
Even though the model fits perfectly in Fusion, the printing quality and material offset for the gear though slight affected it. I need to lasercut the gear again just slightly scaled up and it should fit better. The gear, due to its diameter also makes the turn quite slowly, hence “Worm Gear”. I can change the diameter according to speed.
I added electrical tape to hold threaded rod in place with a little bit of glue to make sure it didn’t rotate.
It was a bit tedious to make sure alignment of thread and gear were correct. It is slightly above the gear itself. Also this is a right turn thread, if turned to the left the thread jumps on top of gear.
Adding holed to base and side walls that would hold thread in place.
The second version was better in its detail but was still a bit to big for the gear so I filed and sanded it a little.
Left: First prints imprecision did not fit into gear. Right: 3D prints, the left one is a second version scaled up slightly and using simplify, the right is the first print using Cura.

Analog Gears: Goal:
These are images of a worm gear and worm for a turntable. Will make to use for a hand cranked turntable and the base of machine.
