Cyclone Filter 2.5" Shopvac Hose Adapters

thingiverse

This is a set of 2.5" hose adapters (large shopvac hose) for Dronnn's well designed cyclone vacuum filter design, which you can download here: https://www.thingiverse.com/thing:2829268 These adapters feature an aerodynamic transition to give larger chunks of debris a better chance of making it through without clogging. Both of the straight and 90 degree inlet styles are designed to be attached to the filter inlet with a friction fit. Glue may be used if you desire a permanent bond. If a more secure fit with the 90 degree inlet is required, I recommend using a set screw instead of glue, in case you need to use smaller hoses later on. Ensure the set screw does not penetrate to the inside where lint can snag on it. The outlet adapter is designed to be glued to the filter top. I printed my filter and adapters in ABS, and bonded the outlet on permanently with acetone. You may need to use CA or epoxy if you print with other filaments. Removal of the outlet adapter should not be necessary since smaller hoses can still fit through the outlet if required.
