VACUUM CUFF ADAPTER 2" (50mm) to 1.5" ACCESSORY

I've used the word “standard” in the brief description above, but there doesn't actually appear to be a standard.  Each manufacturer seems to deliberately make tools a few millimetres different to the other so they can't be cross swapped!

This adapter tapers from 30.5mm to 31.5mm and fits my accessory wand bought separately.    Print fat side down, in PLA is quite OK, PETG as an alternative no supports are necessary.   I always print items like this with a 4mm nozzle and 0.2mm QUALITY mode on Prusa Slicer, as the small additional time is a tiny price to pay for a part which is going to last a very long time.

I also like to use a bit of plumber's tape - PFTE (teflon) to make the friction fit a little smoother.
