Vacbird 3D Printer Accessories Upgrade Vacuum Kit, 20pcs 3D Filament Vacuum Bags with USB Pump (30 * 34cm) Reusable, for 3D Printer Filament Storage, Protect Filament from Moisture

Nice simple little filiment bags and sealer. The pump comes with a usb a & c so you can even run it from your phone. The bags are a nice size and easily fit a 1kg reel in. Not a tight squeeze like some others and the pump is simple to use just put I over the blue disk and press the button. I found the easiest way was to make sure it's on a flat surface. The bags are well made and not just a cheap freezer bag with a valve. Would highly recommend it as a inexpensive but excellent way to keep your reels in good health

Pleasantly surprised with this. Watching their video, didn't think it would suck that much, but I think they're demonstrating incorrect fitting or something in the video, cause once you get it right, it sucks the air out pretty quick (obviously get as much out as you can first!).The great thing about these is that the valve is flat, virtually unnoticeable, unlike some others with a massive plastic cap - so they fit nicely back in the filament boxes (they always seem tight fit so I didn't want big plastic valves)Some people seem to have trouble getting the 'seal' right, but I haven't had a problem. Just put 3 fingers either side of it underneath, and you can hear the sound change.The pump is very nice too - has a USB-C adapter built in to it, and nice finish, nice cable, and nice fancy rubber cable tie.Bags seem very good too. I have some filament sealed up for a week now, not noticed any leakages.

I have used 5 of the bags and one of them 3 time, had no issueIs a bit fiddly to get the pump and valves to hook on correctly but the rest is easyOne note: make sure the valve is on a flat surface before pussing the pump on it and try to store it with no creas or bent on the valve area

Like me I see some people are having problems getting these to work. I found that if you hold your hand flat behind the seal as yo create a flat surface to push the vacuum pump against then it started working and didn't take long to suck all the air out. I'll have to see hiw long they stay sealed but so far so good

I tried this because I've an increasing number of filaments that I swap between.In use, the pump needs to be powered from a 2A capable USB port, something that I didn't immediately spot. Most of my USB wall chargers would therefore not drive it so I had to buy an extra charger.The pump comes with a USB-C connector and I didn't immediately realise that there is a standard USB-A connector (used in most wall chargers) available by unplugging the USB-C connector.In use I found it difficult to get the pump to connect to the valve in the bags and it isn't always easy to get the bag to seal.My other solution is to use desicant (silica jel coulour changing beeds) in a plastic container. The containers come from the local petfood store filled with fat balls to feed the birds - these are cheap enough that the bird feed is effectively free! One drum typically holds three rolls of filament and provides a quicker way to swap and dry filament.I guess the local birds are going to be getting well fed over the winter...

The 20 bags I ordered arrived in 2 bags with 10 vacuum bags in each. I have opened 1 bag & so far I have tried to seal 7 reels of filament but 3 of the bags will not seal. The vacuum bags that work do work well but the other 3 had a slow leak.

Actually super impressed. I've ordered a couple of different vacuum bags for filament in the past, and these feel just as good as more expensive ones. Good seal, good size, and feel pretty durable. The vacuum pump is also surprisingly nice. USB-A or USB-C, so can plug into basically any usb charger you'll have. Nice braided cable, and just generally feels nicer / more premium than what you'd expect for the price. Took about 10-15s to get a really good "vacuum".Packaging is nice too.Overall very impressed, so much so that I was compelled to write a review.

Perfect for my small 3D printing setup to vac-pac the filaments. Just plug it into the PC and sorted. Very easy to use, and it works.

Great small and nice pump - works well with all the vacuum bags .

Super produits

Ich bin sehr zufrieden mit dem Vacbird 3D Drucker Zubehör Upgrade Vakuum Kit. Das Set enthält 20 wiederverwendbare Vakuumbeutel in der Größe 30 x 34 cm, die perfekt geeignet sind, um 3D Filament vor Feuchtigkeit zu schützen. Die USB-Pumpe funktioniert zuverlässig und ist einfach zu bedienen, was das Vakuumieren der Beutel schnell und unkompliziert macht. Besonders praktisch finde ich, dass die Beutel wiederverwendbar sind, was nicht nur umweltfreundlich ist, sondern auch auf Dauer Kosten spart. Das Vakuum schützt das Filament effektiv vor Feuchtigkeit, was die Qualität meiner Drucke deutlich verbessert hat. Die Verarbeitung der Beutel ist hochwertig, und die Größe passt gut für die meisten Filamentrollen. Insgesamt bin ich sehr zufrieden mit diesem Upgrade-Set und kann es jedem 3D-Drucker-Enthusiasten empfehlen, der seine Filamente optimal lagern möchte.

Fait parfait le job !

Buenas bolsas para filamento, al principio cuesta un poco coger la dinámica de vacío, pero luego lo conserva muy bien y lo mejor, es que es reutilizable.
