Interlocking Dust Collection Hose Connection Fittings

Got tired of my magnetic dust hose collection connectors falling off at the slightest brush and getting dust all over my garage so I designed an interlocking one (yes, I know there are ones out there that you can buy).

Used 1/4 bolts with a partially threaded shaft, regular nuts (that embed in the plate), and lock washers. This arrangement allows you to tighten everything up, and then make minor adjustments until the connectors fit just right for a good tight but workable connection.
