TPU anti-vibration feet Ender 3 V3

Print with TPU, 0.4 nozzle.

inside the ”shoe” are vertical waves that are firm against vertical pressure (ie the weight of the printer) but very flexible horizontally. This absorbs a lot of vibrations without making the printer wobbely.

Disclaimer: I have no special knowledge in this field, I made these feet without any calculations or theory. Empirically they seem to work prety well.
