The Modular Panel System (MPS) is a collection of files that can be used to assemble 3/4" plywood into just about any cubic shape. Currently it includes 3 files:

• MPS - Corner Clamp - Used to hold plywood together at 90deg angles.
• MPS - Shelf Support - Used to support flat shelving.
• MPS - Shim - Used in conjunction with the Corner Clamp, as needed.

Complete verbose instructions for usage including print settings for each piece are on my blog: http://www.akeric.com/blog/?p=3994

Disclamer: This is all common sense, but because lawyers: I am not responsible in any way for any type of accident, damage, injury, death, or cost incurred from using this system: By downloading from any source and / or making these files on any printer / fabrication system, you wave me from from any liability now or in the future. Be smart, use at your own risk, test.
