Spirit Halloween PKE Meter Pinion Gear

thingiverse

When arms are over-stressed, the Spirit PKE's pinion gear may fail due to low-temperature molding, as evident from cold flow striations visible on stock gears. This is a replacement pinion gear that I've managed to replicate with reasonable accuracy, despite my limited understanding of involute gears. It performs well in the propeller and can be printed flat onto the bed using supports, requiring at least six perimeter layers for added strength.
