Corner 90 Degree 3 Slot HD

I'm building a table a small workbench out of some 3/8in aluminum extrusions I got from work. Instead of buying some corner brackets, I figured I'd design and print them. They're on the Ultimaker right now so I'll take some pictures of the finished product when they're completed. They do take some time to print depending on the infill percentage but I'm in no rush. When completed they will be fastened to the extrusions with some 1/4-20 thru bolts. Pictures will be online soon!
