The small metal handles on C-stands were starting to be tough on my old joints. The larger knuckle handles have a rubber cover that feels much more pleasant in the hand, but unfortunately nothing similar exists for the smaller handles. I had never printed with TPU before, but this felt like the perfect time to try. TPU is a flexible, rubber-like filament for 3D printing. I designed a similar handle cover for the smaller handles and printed several of them. After a couple of uses, I can say they are much more pleasant to use. The 3D model can be found here.
