Universal unidirectional 3D printable wheel, originally designed as a replacement for the caster foot of a Bluetooth tower speaker, but adaptable to many other objects that need mobility. The wheel is printed from TPU 95A, which drastically reduces rolling noise compared to the original hard plastic wheel. For the body/bracket, I recommend printing at least in PETG, ideally ABS or stronger materials depending on the load. It can be used for speakers, transport boxes, mobile stands, lightweight furniture, DIY enclosures, maker projects, or any application where you need a compact, quiet and easily replaceable wheel.

Usage: 

Print all plates, then glue with superglue the rod caps on the end of the rods after you pushed the rod trough the wheel.

I personally recomend to print the wheel and the rod caps using TPU
