Universal Vacuum Adapter

This is a universal(ish) vacuum hose adapter. I got tired of printing specific adapters for every tool in my shop, so I made one that fits all my tools. The diameter of each side can increased/decreased using the included screws. The tube is flexible enough to expand or shink on either end so you can go from a wide mouth to a more narrow one, or vice versa, easily. I printed in matte PLA and it has help up well so far. This is technically not a perfectly closed system, but when both sides are tight, I don't think you are losing any suction from the miniscule seam down the middle.
