Universal Focus Spacer

The Universal Focus Spacer is a very useful add-on for makers that have multiple laser modules. This will let you quickly focus you laser to the ideal focal distance. 

This spacer works with the following modules:
Ortur LU1-2, LU1-3, LU1-4 (29mm)
Ortur LU2-4 (12V/24V) (50mm), LU2-4 SF (2mm)
Neje 30W, 40W, 80W (19mm)

The unique "hook" design allows you to hang the focus spacer off of the aluminum extrusion frame of your laser.
