About this 3D model

I design this for my mother-in-law who was suffering from cancer. The design was intended to strap the foot that will not fall and drag the foot when pushing the wheelchair because she can't move her right leg. Additional materials: 2xM4 Bolt and Nut 1xM3 Bolt and Nut 1x1inch wide Garter (length as per user) For both legs: Print 2x the STL files and double additional materials.
