LEGO Storage Brick Anti-Stuck Rings

This is my second iteration of inserts for LEGO® storage bricks and heads. My first version was made from PETG, but the rigid material didn’t work well, they got loose in the end.

With TPU (A95) these rings are flexible, press-fit perfectly, and solve the issue of tiny bricks getting trapped at the bottom. TPU is simply the perfect material for this use case.
