Snap on hook for Crutches

This accessory was born out of calamity.
As I was riding my bike to go on a date with my beautiful and talented girlfriend, my bike chain popped off and set me on an unsteady course. I ended up crashing into a telephone pole fracturing my patella and spraining my wrist. OUCHY :(

I underwent surgery and found myself unable to carry the things I normally would such as my emotional support water bottle. After some thinking, I decided to print the problem away.
It's been supporting a full 1000ml Nalgene ever since.

Carful not to overload this hook and be cautious when using.
