Ozark Trail hand pump to vacuum bag attachment.

thingiverse

I store my filament in a garment storage vacuum bag with desiccant, but changing it late at night can be problematic since firing up my vacuum creates noise that disturbs everyone. I remembered we have an air pump designed for inflating and deflating wading pools and air mattresses that has high volume and low pressure output. However, this pump doesn't come with any adapters suitable for the storage bag. OpenSCAD comes to the rescue! I use a funnel script I had found a few months prior, adjust its settings, and add some extra lines of code to create locking tabs. The result is extremely effective!
