Smart Vacuum Filament Container

As someone who only prints functional parts in black or white and does not need large storage solutions of open filament using two of these is perfect for my needs. It seals very well. It is very nice just plopping filament spools in and pressing the top button and it vacuuming by itself over the next minute. While under vacuum I am not physically capable of pulling the lid off with my hands. I would have to break them to get the lid off. The walls on two sides do bow in a bit under vacuum but it doesn't seem to matter. Can't think of anything wrong with them, they are perfect if your someone who just wants convenient access to a few types of go-to filaments for prototyping or whatever.

I had an old roll of pla which wasn't printing too well because it obviously had absorb moisture. After 18 hours in the storage tub, it was like new! Producing clean prints. Well worth the money

After nine months this is still holding a vacuum on one recharge of the batteries, so I’m pleasantly surprised!!!
