DIY 3D Printer filament storage vacuum pump

I've been using vacuum bags for a few years to store 3D printing filament and protect it from moisture. Some people use dehydrators and other dryers to store filament. I really like Airlock vacuum bags, they're pretty tough and last a long time.
I started using vacuum bags with a manual pump but its hard work. The Airlock electric pump is really good but it'd would be awesome if it was faster.
So thought I'd have a go a building a more powerful vacuum pump.

Pretty cool design. I bet if you included some sort of o-ring or rubber seal it would be a lot faster. You're probably losing a lot of performance with the hard plastic. Maybe even try printing it out of TPU.

Thanks.
I tried it with a regular vacuum but that didn't work, had no idea if the valve was somehow special.
Thanks your video I knew it's not, tried again and eventually it worked.

Thanks for show casing the bags. I can replace the cheap ones i currently have when they rip.

Nice job mike, thanks for sharing! Looks like those pumps you used take in about 0.5A, so if you're using a decent charger of at least 2-3A you could probably connect them all in parallel to the same USB port, which would make this much more convenient! :) Just a suggestion, your project is great.

I'd be curious to know if using multiple pumps will increase the maximum vacuum, or only increase the rate the air is moved.

Hmmm might not have been a perfect seal because of the hard plastic? Perhaps you can put a silicone gasket on there. Might see an improvement in the suction speed.

Just discovered your channel and subscribed. You've made some cool projects so far. I can understand the compactness of using a small vacuum pump and it's a neat project, but I just use the hose from my vacuum cleaner. Much faster. I also have a small battery powered Milwaukee shop vac that works even better due to its small size.

What takes longer to pump the air out, the hand driven pump or the electric pump?

[nickwaldron]

Are you using seiko rolling air pumps in reverse or using the inlet valve to generate suction? Also, would it be possible to get an stl or 3mf so I can try it with a single one?

Awesome project .. the lid indeed is a bit cramped.. could you adjust it a bit sothat the three holes for the wires coming into the pump are a bit larger and the height of the lid be extended to f.i. 1 cm instead of the 6 mm it is currently ??

I saw 45 seconds. you holded longer when no air was there

Hello from Ukraine. Excellent job. Can you share STLs? Thanks
