Weed Whacker Attachment Hanger

I wanted to hang my weed whacker attachments on the wall in my garage. I decided to design a snap-in receiver for the attachments and screw an aluminum T-slot rail to the wall. The hanger I designed will slide into a 20mm T-slot rail. I used a u-joint so the attachments could lean against the wall at whatever angle was best.

This hanger was created in Openscad and can be modified for any desired wall hanger. The ujoint library (https://www.thingiverse.com/thing:125939) used was designed by https://www.thingiverse.com/celer/about
