Miele Vacuum Cleaner Hose Connector Complete C3

A replacement part for a Miele vacuum cleaner of the Miele Complete C3 type. It replaces the factory-installed hose connector, which unfortunately, due to its design, has always quickly become leaky over many Miele generations, causing loud whistling noises during vacuuming. No idea why Miele doesn't address this themselves!? - Therefore, with this replacement part, special attention was paid to rectifying this known weak point of the original, making the material thickness at the affected area (above the release clips) significantly thicker so it should no longer wear through. The original hose already holds itself in the connector, but for tough daily use, I have also designed a screw-on sleeve that can be screwed over the connector once the hose is assembled. For this, I used 4x M3 nuts and 4x M3 8mm screws for fastening. This should prevent the hose from slipping out even under strong pulling forces. I printed the parts in PETG, 70% infill and with "enable Support". For printing the sleeve, I also used "3DLAC" as an adhesion base to prevent the sleeve components from tipping over during printing. - Based on my own tests, I advise against printing with PLA, as it lacks the necessary flexibility when pressing the two release clips on the hose connection, and the clips break very quickly with PLA. - It remains to be seen how durable the PETG part will be in daily use on the vacuum cleaner. Edit 02.06.2026: I can report that after a good 6 months of tough daily use with multiple uses every day, the replacement part performs excellently, and it seems this part truly lasts better than the original Miele part…
