Just a simple holder for a Garmin GPSMAP 64

I took the "Garmin Mounting Clip by HAMMER_T August 23, 2018" from thingiverse and made some changes to get a simple holder for a Garmin GPS MAP 64 S.

The changes were: 

• scale in z-size by 2.5 %, to get more room to click in.
• made a bigger backside to get space from the wall
• put two holes in it to fix it on the wall
