A customizable tube/hose/etc. adapter - measure the things you want to connect and make a perfect fit.

In my case, the Carvera Air CNC has a 22mm vacuum input, and the Dewalt StealthSonic vac has a 2.25" hose connection. It seems likely that a 22mm CPAP hose will fit the CNC, but nobody sells CPAP to vacuum adapters (I'm picturing the Scream Extractor in Monsters, Inc.). PLA doesn't have much give, so some adjustments might be necessary

I'm uploading as Customizable, but untested in the Customizer. Good luck, and please post any makes/uses!
