K40 Laser Exhaust Adapter For 4" Vent Tubing
thingiverse
I recently picked up a K40 laser and needed to get proper ventilation setup. To use this, you will want to print out the shorter duct created by "Corey" here: https://www.thingiverse.com/thing:1627210 I then designed an adapter that slides into the back of the laser where the exhaust brackets are which allows you to connect a 4" exhaust tube to the exhaust. I bought the tubing from Home Depot and this inline fan to pull the fumes out of the machine: https://amzn.to/2DBn2aM I printed the adapter in PETG and the Spacer in TPU to act as a gasket between the shorter duct and the adapter that I created. So far I am very pleased with the end result.
