Leg Brace

My child suffered a lower leg fracture in an accident. After the cast was removed, the doctor recommended bed rest. However, as my child is still young (2.5 years old), it's difficult to prevent them from using their leg. Therefore, I designed this leg brace for immobilization.
The brace is designed according to my child's lower leg and foot measurements. For use on different individuals, it is recommended to measure the dimensions of the various parts of the leg and foot first, then scale the model accordingly.
It's important to note that this brace is not a perfect fit and cannot replace medical devices. It only provides basic protection and support.
To secure the brace to the leg, elastic bands can be threaded through the triangular holes (originally designed for ventilation) and wrapped around the leg for fixation.
Note: The model consistently shows non-manifold edges. I have tried several repair tools, but haven't been able to fix them. However, the actual printing effect has not been affected, so I haven't made any further adjustments.
