The bracelet turned out to be quite soft and very similar to the original one. The only drawback is the holes for the clip, they seem narrow when fastened. This is because my TPU filament is stiffer.

But I didn’t make them wider because I’m afraid that the clip won’t hold tight enough. Perhaps if you take a softer TPU it will be easier to fasten. I solved the problem by digging out the hole I needed a little with scissors. 

I took a metal clip from an old bracelet. If necessary, you can print it by taking the project from here:
