Printable E3D Titan Extruder pinion gear

Needed a temporary replacement pinion gear while i waited for a spare one to arrive. There were none on Thingiverse that are truly printable. This design is.

Designed with 0.4mm nozzles in mind.

I printed it in PETG, and it's much tougher than I had expected. This might last a long time.

Update 2018-07-06: After one month of heavy use no visible wear. I'm impressed by the strength of PETG.
