Companion Cube Enclosure Parts

This is a set of Parts designed to create an enclosure for a 3D Printer. they should fit over the edges of 1/8" plexiglass/acrylic. 16 3/32" x 3/8" disc magnets hold the door in place. The illustration shows 16" x 16" panels for the sides.
Edit:
Added "seals" that should slide between the corners and edges, making a more airtight seal. They will need to be glued onto the door in order to make the seal complete.
