Replacement Pinion Gear for RC Wheely Truck

Replacement gear printed with ABS, 15 tooth 16mm in diameter. Original did not last long and replacement kit costs about $10. Designed on Sketchup and increased the thickness significantly since there is lots of head space in the gearbox cavity. Much stronger and should last long. Costing less than $1 to print about 10 of them.

Don't judge the battery pack hehehe. Strung together a bunch of Li-ion 18650's I had around and replaced the original 7.2V NiCd pack. Now I play until I get bored and
