The gear is printed in black silk PLA for this first test and the worm is printed with powdered nylon 11 on a Formlabs Fuse 1. PLA is really cheap and prints MUCH faster than the Nylon 11 so its perfect for prototyping.
Once I have the design finalized, my plan is to print the gear out of the same Nylon 11 as the worm. At least as a sleeve that will go around a carbon fiber nylon filament printed hub.
The goal of this was to keep costs low but also make it efficient on power which is why I didn't go with a nema17. This little motor only needs 0.8A and also keeps the weight down in case I decide to travel with it.
I think so far I have about $75 into it including motor, bearings and hardware. Motor was the most expensive part at about $55 but they can be found about half the price from China
Here is another picture showing all of the components:
