A good friend of mine has Ehlers-danlos syndrome. Ehlers-Danlos syndrome (EDS) comprises a group of inherited heterogeneous disorders that share a common decrease
...Plus in the tensile strength and integrity of the skin, joints, and other connective tissues.
For her, one of the ways this manifests itself is hyper-extension of her fingers that causes painful swelling.
One day she showed me some ring-splints that she could buy on line, but they where VERY expensive and I thought... Wait a minute... I can print that...
So, here are my Ehlers-danlos ring-splints that she wears now every day. A complete set for her costs about 1$ worth of flexible filament and takes 15 min to print.
I'm working on how to make this a customizer app so it's easier for others to make ones that fit them, but I have found that just scaling these up or down in your printing software works well.
She has been wearing them for a few weeks now, and they apparently work very well. Going to be making her a new slightly smaller set as well as they are fitting a bit lose now due to her swelling going down.
I hope these can help more people out there as well!
