Tamiya Lunchbox/Midnight Pumpkin 12mm Hex Adaptor

thingiverse

This is an adaptor to allow you to fit wheels on the back of your Lunchbox or Midnight Pumpkin that have 12mm hex drives. The standard Lunchbox or Midnight Pumpkin wheels are a very unusual size and fitting type so finding decent tyres or hubs is almost impossible, with these adaptors lots of standard rc car hubs will fit. Print upside down, with the 12mm Hex at the bottom, this allows for the small protrusion on the other side to be printed. The protrusion is needed to allow the adaptor to transfer axial loads into the out bearing rather than going through the diff gears.
