Download Free 3D Model Mini Toy Tank Track 3D Print Model

Summary
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!
How I Designed This
Fushion 360
I used Fushion 360.
Initially I thought of drawing like an rectangles with two semi-circles at the two ends but realised that it cannot be printed properly. Then I realised that using TPU, a circle will be a better shape since it is flexible.
So I drew a circle, extruded it into a “rubber band”.
Then created a plane on the tangent and dew one of the tyre outline, extruded it, then created a pattern around the extruded circle.
