A simple fixture to hold a vacuum pump to suck the air out of my 3D print filament bags I use for storing partial filament reels. The USB vacuum pump was bought on AliExpress and there are a lot of models that all look the same so you may find your's will fit this too.

I've included both a Lite Multipoint Rail version and an "old style" Push Fit version for adding it to your Multiboard. I've been using Multiboard for over a year now and, if you're like me, you will get brain freeze whenever you try to think about how to connect the various fixtures together 😁. With over 10,000 ways to link any two parts it's a great system, but "simple" is definitely not how I would describe it 🤣.
