I wanted a way to quickly mount and dismount a ring light for my galvo laser so I designed one that uses magnets. 

This is very specific for my machine due to the style of arm and galvo head that I have so it may not work for you. 

Materials: 

(12) 5mm x 5mm neodymium magnets that need to be press fit with an arbor press or similar device

(2) M4 x 10mm bolts

(1) ¼-20 1.25in hex bolt
