Cup holder for crutch

thingiverse

This is a cup holder designed specifically for use with 22mm diameter crutches, as seen in the picture accompanying an Emsa thermo cup. The holder measures 70mm in height and features an inner diameter at its bottom of 70mm, expanding to 80mm at the top. This design was created on short notice and hasn't undergone refinement since it functioned perfectly for my needs. To prevent slippage, apply a small amount of rough tape to your crutch before attaching the holder.
