D27 hose osVAC connectors with slip ring: compact and hassle free (Fits Festool D27)
Minimalistic and easy to print hose connector for D27/32mm hoses like Festool and Bosch. The design is as narrow as possible, this avoids collisions with the work piece, especially for use with sanders.
The slip ring function is similar to the osVAC neo design. Print the bottom and top parts separately. To assemble, position the two pieces together and push a piece of filament into the side hole of the bottom connector. Cut the filament so that a short section is still sticking out as shown in the photo. Take a lighter or a small hot air gun to heat the filament stub until it is liquid and seal it with a flat head screwdriver. Alternatively you can also just cut it off a bit shorter and push it into the connector with a piece of filament.
The female adapter uses my osVAC leak tight modification. You can add a 37x32x2.5mm O-ring to achieve an air tight fit, a really cheap one will do. Without O-ring, it will work as any other osVAC connector.
