My Kid Loves Ultraman, and here there is hardly any toys for him, so I went ahead and mocked one bracelet from his super hero.
Still a work in progress but surely he will love it.

Not sure the size is right so I will print it and then figure out the sizing in the 3D model. Once I get that I will update the file.

Also, due to not wanting to print rafts and supports I made it in two parts that can be glued together.

Future updates might have rafts but it depends on how this prototipe goes.

I'm planing on adding elastic to hold the bracelet tight in my kids arm.
