(Maybe) Building a new case for Bangle.js 2

I wanted to have a go at FreeCAD and thought designing a case for the bangle would be nice to try out modeling something to actually build for the first time :)

Wishlist:

1. USB-C for charging
   
2. Buildable by me
   
3. Not a lot thicker than the original case
   
4. Rugged (primarily better screen protection)
   
5. Screw on back.
   
6. Maybe even waterproof? (Found waterproof USB-C ports on ebay)
   
7. Keep HRM
   
   

TODO:

1. Try making space for a bigger battery (36x25x4 330mAh might fit with about a millimeter more thickness)
   
2. Simplify band mounting (just loops for textile straps maybe)
   
3. Solution for mounting internal components without to much glue
   
4. Find out if I can actually build the thing
   
5. Find out if the HRM can be removed from the original case without being destroyed
   
6. Refine the hardware mockups for better internal space representation
   
   

Has somebody attempted something like this? I am sure this will take some iterations and probably fail in the end but no way of knowing without trying, eh?

I have an old manual proxxon desktop mill that can do about 0.1mm precision and some other tools and want to do this in aluminium.

I'll attach the FreeCAD file but be assured that it probably is not well done as I do not have experience with it or CAD at all.
