Modular and re-usable plywood furniture connectors

Use these connectors along with plywood, MDF or other panel products to make modular, customizable and re-configurable furniture.  You can make tables, shelves, foot stools, computer monitor stands or other organizers.  These are great for student dorms, kids rooms and other places that get moved or re-configured a lot; you can take them apart, they pack down flat for storage or moving and you can re-configure them again and again.

The insides have little ridges to help hold them in place.  They are very sturdy, I can stand on a shelf without it breaking, but to be on the safe side, don't use these for ladders or step stools.

The included models and print files work perfectly with nominally ½" plywood, my plywood measures out to 0.508 inches or 12.9 mm thick.  But, plywood comes in all different thicknesses and is not always consistent.  After you find whatever plywood you are using and have it sanded and finished as you like, measure it with a caliper and scale the model files as needed.  They should scale well for a wide range of thicknesses, so you could scale it down to fit ¼" (6mm) plywood or up to ¾" (18mm).  To check the fit, scale and print the ‘foot’ (it is the smallest) to test. 

You could use the most versatile ‘middle’ model for everything or make it a little tidier by using the ‘corner’ and ‘edge’ pieces as needed.  You might not need the ‘foot’ model at all, but it is small and quick to print so it makes a good test piece to make sure the fit is just right.

I added a set of scaled down pieces to fit nominally ¼" plywood.  The actual thickness of the plywood was 0.214".  To scale it I took the size I needed, divided it by the size that fits at 100% (0.508") and multiplied by 100 to get the scale factor in %. (0.214"/0.508")x100=42.1%.  I used these mini versions to make another small shelf and some drawer dividers.  The foot doesn't work scaled down this far, the skinny side gets too thin to print.
