Adjust my 3D watch case to use available parts on the market

I need someone to adjust my design without altering the look to fit commonly used part such as
- sapphire crystal
- stem
- movement
- movement holder
- crown
- o-ring
- gasket
- screws
The watch size has to stay the same
52.5mm lug to lug
41mm wide without the crown
8.6mm thick from glass to back of the case
