20 x 20 Extrusion Triple corner

This model was made in order to create a custom enclosure out of 20x20 aluminum extruded profile. When made with organic supports (recommended), it creates a support in the middle that's rather hard to remove but, in my opinion, it's worth it for the alignment that this print provides. 

The Gcode is set up to print 8 at a time using organic supports. The print in the picture was created from that file, and was printed in Overture matte PLA.
