I had a beloved watch whose band snapped while I was working, so instead of buying a new one, I 3D-printed a replacement. What's innovative about this band is that it enhances breathability by exposing the gyro mesh structure. When I actually put it on, it's comfortable without any sweating.
Using TPU filament. I believe the softer one is more suitable, but feel free to try it according to your preference.
When downloading the STL files for printing, it's important to align the positions of bandA and bandA_mesh, as well as bandB and bandB_mesh as closely as possible. Set the layer stacking for the top and bottom surfaces and the boundary to 0 for bandA_mesh and bandB_mesh. Use a 25% infill and enable gyroid infill.
