Duct adapter 6" to 4"
thingiverse
The Orion Motor Tech laser has a 6" exhaust fan. I had a 4" duct I could work with. This is a adapter I created with an offset to it fit my classroom. Took about 7 hrs to print on the MakerBot replicator+. It has been working like a champ as I wait for a 6" hole in the wall to appear. https://youtu.be/hd23sHW1mhw
