The R Credenza is a compact hutch that takes shape out of a single sheet of plywood, cut by a CNC router. Made of just seven pieces, it snaps together with precise mortise-and-tenon joints and fat yellow ratchet strap. Sliding doors conceal three linear feet of storage, neatly compartmentalized by two nylon dividers. The name derives from both the fastening system and the side pieces, whose form echoes an abstracted "R."

I don't own a CNC machine. This project was prototyped at the Fab Lab Baltimore, a makerspace that provides low-cost machine time as a community service. If you don't own a CNC, search for a Fab Lab near you; there are 74 in the U.S. and over 400 worldwide. I am hosting the actual cut file as a download on my site, or you can gather enough from this Instructable to draw your own in CAD.

The R Credenza is an open-source object: its source code is available, and I encourage anyone who downloads or copies the design to hack it, improve it, and post the results here! Post your work on social media using the hashtag #OSOdesign to follow other makers creating open source objects.
