Exhaust Duct Adapter

Summary

Exhaust Duct Adapter
for Snapmaker or other exhaust hose with diameter of 75 mm (approx. 3 inch)
In order to clamp the exhaust air hose (diameter 75 mm (approx. 3”) of my 3D printer in the window frame, I designed an adapter with FreeCAD (file enclosed).
This adapter consists of three separate parts, so that the individual parts can be printed separately on smaller machines or individually adapted.

  1. Round nozzle with bars (connection to exhaust air hose),
    H: 70 mm, diameter: 75 mm,
    Printing time approx. 6 hours
  2. Transition with connection
    H: 90 mm, W: 155 mm, D: 25 mm, diameter: 74 mm
    Printing time approx. 14 hours
  3. Rectangular nozzle with bars and supports
    H: 65 mm, W: 155 mm, D: 35 mm)
    Printing time approx. 14 hours

The parts are designed with zero tolerance and can be plugged into one another. Eventually they must be carefully reworked with a file to make the parts fit perfectly. They can optionally be glued or screwed together.

Interesting side effect:
As long as I was employed I drove with a car to my company (automobile manufacturer) in order to be able to afford a car.
Now I have a hobby to make parts that I need for my hobby.
