Another K40 Laser Cutter exhaust adapter. In this case designed to be minimal. A one piece version and a two piece version is available. If you are printing on a 3D Printer with a small build area the split version may be better. The yellow one in the picture was printed on an UP! Mini at 100% infill. I cutout a gasket to put behind it on my machine to help with the seal. Also provided is the Rhino 3DM files to make it a little easier if someone else wants to make improvements.
