Remix of the Drive Gear for a stronger grip to the shaft.

The original gear works good in most cases, I've had to replace mine on a regular basis though. I've printed them in PLA/PETG/PETG-CF/ABS and all last a few weeks before giving up and slipping on the shaft. The shaft temp doesn't get too hot, I measured the last time and it was roughly 35c. I've added an extension Boss to the Gear to provide a bit more surface area to obtain better reliability.

Important fitting instruction. The tolerances are tight to ensure a good fit, due to this I recommend sitting the motor in the freezer for 20min while the Gears are printing. Once they have finished, immediately press fit the gear onto the Motor while there is a wide temperature gap. This will help fitment as the gear will shrink as it cools and equalises. Leave the motor to warm up slowly in the fresh air to avoid excess condensation.

Have provided two on the plate, one ABS and one ASA. Up to you if you want to change materials. They are print by object, but again that is entirely your perogative if you would like them both printed the same :)
