Hose Reductor (For Crank Case Vent)

3D model designed by Sedowynt using Autodesk Fusion (360) Personal License. This hose reductor was originally designed to facilitate the use of an aftermarket crank case vent filter on a MK6 (1995-2004) Ford Escort, housing a 1.3 CFi/H Endura-E engine. I used the stock hose (shortened), and mounted the filter with a steel band using an already existing hole on the intake manifold. I chose a crank case vent filter made by Simota, with an 18mm hole. You would use this solution if you're not using the stock air box. This doesn't mean you can't use it for anything else. Just keep in mind that the 18mm side is 2mm shorter (18mm side is 14.8mm-, 16mm side is 16.8mm long). I printed it from PLA, witch should be fine, although something more resistant is preferable. The only thing you have to make sure is to print it with 100% infill.
