I was looking for a cheap way to package the filament in a vacuum bag. The Zip bags are very cheap to get, but with existing vacuum adapter, for me very expensive.
You need only one from each cutting adapter. There all have a bottom and nothing can happen will you cutting
From the other parts print as much as you need for your vacuum bags.
A construction manual is available at: https://www.1-2-do.com/projekt/vakuum-adapter-fuer-zip-beutel/bauanleitung-zum-selber-bauen/4011594
this is only in German. But there are enough pictures available to be able to replicate it exactly.
Have fun!
