Replacement feet for ALU-ladder

Replacement for broken plastic feets for ALU ladder with 62x20mm profile size.

I made it in PETG, with 1mm additional space (if the ladder is alteady bended..)

If it is too lose, you can use silicone to glue it in (or for example tape to fill up the gap)

Used thicker outerwall in slicer (10 times) to increase stiffness. But i think less would also work.
