Mini Toy Tank Track

thingiverse

So my 3yo son asked me to fix his toy tank tire track. I didn't have any TPU on hand but decided to test it out with PLA first before my TPU filament comes. I printed a different design at first but realised it can't work as the tracks cannot be properly drawn around the sides so this circle design is a better one. TPU is flexible so we should be able to bend it around the longish shape of the tank tracks!
