Open AFO (Ankle-Foot-Orthotic)

thingiverse

This is the Open AFO. We designed this as an improved, custom-fit version of professionally-made AFOs because we think these should be affordable for everyone and because we think the AFO should fit/conform to the person's foot. We used TPU, but this could easily work with PLA or ABS materials. Update 18 Nov 2021: Uploaded the STL for the hinge. We attempted two types of hinges: 1) We re-used a set of hinges from a commercial pair of old AFOs. Unfortunately, these hinges can't be purchased directly because of medical patents. 2) We printed some hinges using TPU filament. Varying wall thickness and infill changed how stiff the hinges are and you might have to do some trial and error iterations to make it work for your application. Update 18 Nov 2021: added IGES files if someone wants to edit the CAD.
