3D model description
An adapter for the cheap eBay 40 watt laser cutters to let you attach the hose directly to the back of the cutter. This allows you to use an in line blower fan, which eliminates positive air pressure in the hose and lowers the chance of fumes leaking into the room.
3D printing settings
This was printed on a Stratasys BST 1200 as a single part.
The dimensions shown are in mm.
The part was just a tad too long to fit in the bracket, but it filed down very quickly. I've included the original solidworks file if you want to modify it (obviously give credit where it is due if you post somewhere)
The hose barb itself fit perfectly with the hose that came with the laser cutter.
If you have an imperfect seal between the laser cutter and the adapter you can try laser cutting a seal out of cardboard or cut some rubber to fit. It was not needed on mine but the quality control on those tabs doesn't look like it's the best.
