Vacuum Adjustment Nozzle

This print-in-place vacuum nozzle variably reduces the cleaner's suction to about 50% when fully open.

Print vertically as shown in the last pic. The .3mf and .bgcode files were created using two separate .stl files. I've since combined them into this one file for convenience.

The print requires considerable(!) torque to break free the two pieces. After that, the sleeve spins freely around the nozzle.

Printed in PETG for strength. I used a 3 mm brim on both the inside and the outside for stability. No other supports are needed.
