GPS Phone Holder

I printed the main base and the bike attachment in 20% cubic /!\ BUT the screw in 100% /!\

2 metal screws are necessary to hold the 2 parts together.

To have a screw of the right size I made 3 models of screws:
- 15mm for phones between 8.5cm and 8cm
-25mm for phones between 8cm and 7.2cm
-35mm for phones between 7.2cm and 6cm

if your phone is between 2 sizes, take the larger screw the result will be better.
