K40 (Red&White) Exhaust Port Panel
Description
I designed this to replace the thin and poorly under-designed k40 (Red and White) exhaust flange that mounts the exhaust fan to the back of the laser. Th outlet is well under the 4in diameter and fairly short, making attaching 4in exhaust duct difficult. This will not work with other style exhaust panels. This can be printed with any profile, however I chose a .8 nozzle with extra wall lines and 50% infill to add extra strength. The bolts to mount the fan, do need to be exchanged for longer bolts. I used 4 nuts and bolts from a box I had in my garage. Admittedly, it can be altered to have the heads of the bolts countersunk for a cleaner look and use the stock hardware. I might do this in the future and update the file. The holes matched up perfectly for my machine, but you may need to clean them up with a drill bit depending on accuracy and your machine.
