Ozark Trail hand pump to vacuum bag attachment.

thingiverse

I store my filament in a garment storage vacuum bag with some desiccant, but when I change filament late at night I don't want the noise of firing up my vacuum to evacuate the bag. I remembered we have a nice high volume low pressure air pump for inflating/deflating wading pools and air mattresses. But it didn't have any adapters that would fit the bag. OpenSCAD to the rescue! Grabbed a funnel script I had found a few months back, tweaked the settings, added a few extra lines of code to add locking tabs. Works like a champ!
