Z-Rack Bottom Shelf Bracket

After being inspired by Stanfords d.School "Make Space" book, We followed their instructions for creating a low cost whiteboard out of a garment "z-rack" with a few of our own changes.

This part was created to add a minimal bottom shelf to our z-racks, allowing us to rest foamcore and cardboard sheets on the shelf.

Part Details:
- Hole opening is sized for a #10 flat washer
- Bracket sized to fit around two sheets of .125" showerboard
