Vacuum sealed storage bag pump adaptor

This adaptor fits the header of a pump used for vacuum sealed bags which I bought on Amazon.  There are two versions - the tubeless straight adaptor and the separate-but equal adaptors that are connected by a tube of diameter 5.2mm (OD).  Attaching both ends to their respective sides before power up makes it easier to walk away whilst it sucks out all the air from a bag of pillows, sheets or clothes.  Takes about 8 minutes per bag (kinda slow) but at least you can ‘set it and forget it’

Here's a link to the item on Amazon:

The OD of the vacuum pump nozzle was 26.7mm and this object, printed out in a resin printer will create a friction fit around the nozzle.

Prints without supports in your resin printer.

If you found this useful, it would bring me great joy to see your work - so be sure to share. :)
