Fiber Laser Air Duct (Cloudray and Gweike)

This duct can be used with fiber lasers with threaded bases.  The mounting holes span between 100mm and 112mm.  It works great on Cloudray and Gweike fiber lasers.  It adapts to a quick-disconnect duct.  The magnets are 12mm x 8mm N52.  They are press-fit, but glue can be added if necessary.  Part is printed vertically with tree supports, rectangular duct facing the bed.

The duct coupler uses the same magnets and is made for a 3.5" hose.  It gets printed face-down (handle pointing up).  No supports are necessary as long as you can bridge reasonably well.  There is a drawing for the coupler if you'd like to design your own.
