Shop Vac 2 1/2 to 1 1/4 Reducer and Zip-Lock Bag Air Extractor Adaptors

thingiverse

A vacuum nozzle adaptor to evacuate air from Zip-Lock bag for storing filament rolls. Well, that's how it started ... My little battery vac just didn't have enough juice for the job so I plugged the adaptor onto the ShopVac and it works great! Anyway, I've almost been afraid of the reducer because it makes a deafening whistle so the repeat experience got me to make a reducer that didn't whistle/scream. I think they call the ends 2 1/2 and 1 1/4 ... I measured F58mm to M30mm and my vacuum brand is a ShopVac. Not sure if hoses are standard for Rigid and other common wet dry vacs?
