Mini Toy Tank Track

thingiverse

My three-year-old son asked me to repair his toy tank's tire track. I didn't have any TPU on hand, but I decided to experiment with PLA first before my TPU filament arrived. Initially, I printed a different design, but it quickly became apparent that it wouldn't work since the tracks couldn't be properly drawn around the sides. This circular design turned out to be a better choice. Since TPU is flexible, we should be able to bend it around the long shape of the tank's tracks.
