bogie drive wheel

This is a replacement for Tamiya's standard 1/14 scale drive wheel with hex drive. I have designed a breakout section for the hex part but you must include supports in your slicer for the inside of the wheel. The hubs simply push into the wheel centres after fitting the nut. Included are centres for drive and trailer wheels. I have updated this on 22/1/20. More realistic. Added dual spider without supports for printing with resin.
