Occupational therapy bending stick

I recently injured my wrist and needed to go to occupational therapy for a few months. One of the exercises my therapist had me do was bending sticks. This exercise that involved the sticks was two parts. First, take the edges of the stick with palms up and rotate my wrist inward to bend the stick for a certain number of reps. Then for the second part, I was to do that again in the opposite way with my palms down and rotate so that the stick again bend inward.

I also have some fine motor skill and coordination difficulties with my right hand from a brain surgery I had years ago. So to help with strengthening my fingers on my right hand, I created a small version of that stick. I can flex my finger, especially my pinky and ring fingers, towards my thumb to help work out those individual fingers. 

Each of these sticks need to be printed with flexible filament. Depending on how many perimeters or infill percentage, you can make these sticks customizable to your desired difficulty level. Higher perimeter or infills will increase the difficulty, while lower perimeter or infill will decrease the difficulty. I found these to be better to print with brims to reduce warping.
