Wrist Computer for S3 mini

prototypes were printed with 20% infill, 0.4mm layers, 0.8 nozzle -> worked fine for me.
I gave the final piece to a manufacturer who laser sintered it.

What you need:
Samsung S3 mini
Torch with 13mm diamter (max)
two o-rings 18mm inner diamter and 4mm thick
1.5 or 2mm wire for the hinge
padding
3 small wood screws
USB cable with angled plug (optional)
Powerbank the size of a lipstick (optional)
