Era 1 wheels for 1 Gauge trains (1/32)

thingiverse

Alternative wheels for the great prussian tank wagon from ccs66 ( see https://www.thingiverse.com/thing:3409151) as well as other cars. The wheels are Maerklin standard 30mm size. These wheels are also easier and quicker to print than the wheels included with the prussian car due to the shorter axle tubes. The wheels need additional 3mm diameter steel rods, of ~61mm length. I used a vertical drill with a 3mm drillbit to clear out the hole for the axle.
