Twist-lock Dust Fitting - 1.75" hose clamp end
thingiverse
Modification of SVideo's airlock design; fits a 1.75" vacuum hose. Included a wingnut to tighten securely around the hose, otherwise it falls off. Use an M4 x 25mm bolt, nut, and washer. Make sure you use a strong glue and print the wingnut in a plastic that works with that glue. I used PLA and cyanoacrylate glue for the wingnut.
