Bulkhead Exhaust Fan Housing with Hose Connection, with FreeCAD file

thingiverse

This connects a fan to an exhaust hose for my printer enclosure. The fan I used came from an old computer. It fits within this unit. A hole or slot for the wiring must be made by hand after the part is printed, depending on where you where you want it. The output is to a standard swimming pool vacuum hose tapered connector. I printed without supports. Included is the FreeCAD file used to design it. It is a parametric design, if you care to change various dimensions. (I highly recommend FreeCAD, although the learning curve is a bit steep at times. For beginners, it might be useful to start with a design that already works, and try modifying it.)
