TPU door stop. Easy to print in a few minutes. If the size does not suit your needs you can use the scale function of your slicer and enlarge or smaller according to your taste.
It works well with Overture TPU 95A but it is tiny!
Printed it at 150% and it's much better.
The path the nozzle takes making the circles does cause stringing. Not the fault of the model and doesn't affect its operation, it's the nature of TPU. Seam randomization in the slicer would help and so would careful calibration for the filament.
