A looping for the custom track. This is not compatible with Tamiya manufactured track. Use the connectors and straight pieces from the original design to make a stable assembly.
Printed with a 0,4 mm nozzle and 0,3 mm layer height.
Note that car speed and wheel distance of your Tamiya mini 4WD car detemines if the car can make the looping.
The author remixed this model.
This model adds a looping with a 400 mm radius (800mm diamter) to the base design.
