Lutron Aurora Strong Magnetic Mount

Based on another build, however with more space for more magnets to stick to the area without moving. 

Max magnet space

1 - 15x6 mm magnets 

2 - 10x6 mm magnets

In total I used three 15x2 mm magnets and four 10x3 mm magents

Printed slightly taller to lessen the gap between the mount and the dial, and with a tighter fit on the adapter, which does not require the screw, however still advised. Moved the magnets to be inserted from within the mount as to not scratch your surface, as well as holes on the bottom of the magnet to easily remove the magents after being inserted
