Reduction Gears

Sorry, this is not an Amateur Radio post.

After many months of working with a 3D Printer, I have finally successfully created a working set of interlocking reduction gears, each section provides a 7:1 reduction. This device is about 2 inches in diameter, the total reduction is 14:1.

The original Ring Gear from Thingiverse was modified to create this multi-stage Reduction Gear. My contribution was to modify it as necessary and join two sets together.

Sketchup Model
The transfer plates (with the connecting pins) were assembled by adding the center HEX pin after printing.  Each of the two Reduction Cluster were printer as an assembled single object on the printer. No cleanup or filing was necessary.

Silicon grease is used for lube.

I may increase the size (and with other modification) this could be used as a Light Weight Field Day Antenna Rotor.
