My original Starmix GS 2078 hose connector broke at the vacuum cleaner end. The thin bayonet tabs that hold the connector in place snapped off.

I printed a replacement body (based on the original part available on MakerWorld), but it did not include the inner piece that secures the hose, so here it is.

Assembly instructions:

1. Insert the sealing O-ring onto the hose.

2. Screw the inner part onto the hose.

3. Insert the assembled hose and inner part into the main body.

4. Glue only the O-ring to the main body, allowing the inner part to rotate freely.

I believe this design may be an improvement over the original. The inner part uses an internal thread to attach to the hose, which should reduce the chance of stones or other debris getting stuck at the hose end during vacuuming.

Mine is printed from PCTG.
