Tamiya Lunchbox/Midnight Pumpkin 12mm Hex Adaptor

thingiverse

This is a converter designed to enable you to fit wheels with 12mm hex drives onto your Lunchbox or Midnight Pumpkin, featuring unique wheel sizes and fitting types that make standard tires or hubs extremely hard to find. With these adapters, numerous RC car hubs will fit perfectly. Print the adapter upside down, positioning the 12mm Hex at the bottom. This allows for a small protrusion on the other side, which is crucial for transferring axial loads into the out bearing instead of going through the diff gears.
