Exercise Fitness Physical Therapy Resistance Band Grip

thingiverse

I needed something to exercise my arm after having surgery. I modified a bike handlebar grip and printed it with 25% infill using TPU for a squishy feel. 25% was probably a bit too light, but so far it is holding up. I would try 60% for my next one. If there is interest I wouldn't mind making a second version that can use a PVC insert. I didn't feel like looking for a scrap piece of pipe in the garage so I made the included core. The core adds rigidity via PLA while the outer TPU sleeve gives a bit of comfort. the inner core is just under 20mm if you want to use a dowel or some other rod instead.
