These are stackable tetrahedron (3D triangle) paint pyramids with a TPU tip and TPU feet for a softer contact point and better grip.  No more marring and no more sliding!  They stack for compact storage, and the stylized triangular cutouts make them easy to hang on a horizontal rod or pole.

The TPU is mechanically captured inside the base material, so the body can be printed in PLA or other rigid filaments without relying on adhesion between the two materials.  Softer TPU works best. I recommend 90A, but 95A is also perfectly fine.  I found 85A to be a bit soft for the interlock method with PLA, PETG may work better because it will actually bond somewhat with the TPU.

Each plate includes a set of four pyramids. A profile with flat ~5 mm tips is also included for heavier parts, more stability, or if you prefer a less pointy contact point.
