Cup holder for crutch

thingiverse

This is a cup holder that snaps on 22mm diameter crutches. I use it with an Emsa thermo cup as seen on the picture. It is 70mm high, the bottom has an inner diameter of 70mm and the top has an inner diameter of 80mm. This was a quick design that I did not refine since it just worked for me. Add a bit of rough tape to your crutch to avoid it sliding down.
