This is a very simple and fast printed TPU test, that also can be used as a color-swatch/demo piece.

I made two versions, circle and hex, both chamferred edges.
They are meant to test how well tpu handles edges (hex), turns (circle) and stringing.

These also work great as color-swatches, demo pieces and strenght tests (stretch test).
