3D model of Bangle1 strap

[ps-igel]

Hi all,

the strap of my Bangle 1 has now broken for the second time. I replaced one of the straps already from with a model I made and printed in TPU. However it doesn't look very good. It's also really hard to get the correct measurements, because the shape of the connector is kind of awkward.

And I don't really want to print some kind of adapter only to use a different strap.

Has anyone already created a nice replacement model of a strap?

I attached the one strap I already created.

Hey @ps-igel,

I don't have the 3D model of the watch, but I had built a ruggedized version of the banglejs2 using a printed metal cover with wristband holders. Maybe this can inspire you

That's a great idea! I'm afraid I don't have a 3D model of the existing strap though. I'm afraid for me to get anything I'd really be doing what you are I guess - just trying to measure an existing one.

Does anyone have a 3D scanner I wonder? Maybe you could glue the original strap back together enough that it's kind of the right shape and then post it to someone that has one?

... having said that, I wonder whether normal TPU would be strong enough for everyday use? I guess you could send it off to be 3D printed, but my experiences of the SLS rubber prints I've had done has been pretty poor too. I have seen some places will 3d print a mold and then cast in silicone for you, so that might work.
