This was designed so I could vent my laser cutter in to the vented attic. It accepts standard size dryer vent hose using ring clips or zip ties and can be used to replace a standard dryer vent. Because I as tyring to move a lot of air, I designed the bottom 2 OPTIONAL pieces to allow the addition of an inline, 120mm PC fan. 2" Drywall screws will mount the whole assembly securely to just about any surface that you are trying to vent through. Use 1" if you are not including the fan assembly.
