One sixteenth by three quarter inch Angle Aluminum corner connector

Building a custom rack/case to hold all of my home server equipment. Decided on some cheap angle aluminum for the frame, and whipped up some connectors. V2 has been posted, the parts dimensions have been scaled to accommodate angle aluminum based on my 3d printers tolerances to PETG. The exterior wall of the part has also been made slightly thicker, and a Fillet was added to the exterior as well. Holes are 5.7mm, they're ment to be tapped w/ a 6mm tap after the fact. I'll also probably post a version that takes 6mm heat set inserts too.
