We lost 2 of our feet protectors, that came with the hairpin legs. As a replacement set of 4 costs 10€ I quickly designed my own.
They fit snuggly on the bottom part of the feet but should come off easy enough, should there be the need to.
Comes as two versions, one with text/logo and one without (easier to print).
I printed mine in black PLA, since I don't have TPU on hand (not even sure if I can print it on my machine) but it should work fine with TPU too. Since the original feet protectors are made out of some rubber-like material probably the better choice.
The author marked this model as their own original creation.
