motorized worm gear 1:54 ratio

here is my version of a worn gearbox.
the gear ratio is 1:54
to make this i used a RS-555 DC 12V motor,
some M3x8 , M4x16, M8x30 screws.
2x 608 bearings
small brass tube ØOD 5mm ØID 4 mm , 8 mm long.

assembly:

1. print the parts
2. insert the bearings into the large gear
3. insert brass tube into base part
4. place small gear into place and fix it with M4 screw through brass tube
5. slide in the motor and fix it with 2 screws
6. place big gear and fix it with M8 screw.
7. connect wires and close the cap with 2 screws
8. power the motor

its recommended to use some lube on the gears to make it run better and quieter.
enjoy :)
