Arch Supports

I wanted to try and make arch supports. I have very flat feet and wanted something I could make myself. These were printed in TPU to be flexible. I put them UNDER my insoles and used carpet tape to keep them from shifting. No guarantees for these USE AT YOUR OWN RISK. They were printed at 10% infill with 1mm top layer (maybe should be more since it left openings.) These are less than 6mm at the highest and about 1mm at the low end.
