I got sick and tired of fighting with my Festool dust extractor hose when using my Porter Cable biscuit joiner. I finally decided to design a locking hose adapter. The connection between the adapter to the biscuit joiner is still a friction fit, similar to the original adapter that was supplied. On the connection between the adapter and the Festool hose, you can either just press it in or twist to lock. To be honest, the locking feature is not needed after testing it on the biscuit joiner.
The adapter was printed in PLA using variable layer height to make it look smooth. It's not necessary, but I really liked this feature in the Prusa slicer and had been using it on almost everything. Print it in the orientation as shown in the picture. There will be minimal support needed. Enjoy!
