Filter Turn Screw for Fein 9.77.25 Dust Extractor/Vac

prusaprinters

T-slot turn screw/flange that allows you to use a cheaper (big box store) HEPA filter made for the other, louder brand of shop vacuums on a Fein 9.77.25 Dust Extractor. (Please comment if this works for more brands or models, and I will update the description.)It's possible Fein used to sell something similar, but I wasn't able to find one for sale, and the part was easy enough to model. I hope it works well for you, and I included the Fusion 360 model file if you need to modify it.I recommend printing in PETG or harder material with the point facing up. Supports needed. Add a few perimeters to reinforce the thin neck.PLA not advised since it's subject to layer sheer, but if you need to use PLA, choose a horizontal or angled orientation to increase strength.
