Alright guys I need your help, I finally stripped the pinion gear on my motor, but not the gear itself, just the shaft that is press fits onto the shaft.

I measured my motor shaft to be ~1.5mm OD, can someone please link me some pinions in that range? I would much rather them be brass/metal than plastic.

I currently have a 12 or 13 tooth pinion. So something in the 10-12 range would be nice.

Thanks all for the help.
