I wanted a simple laptop stand that could be easily disassembled and packed in a backpack. Using Autodesk's 123D Fabrication Utility, I created CNC toolpaths that I fed to a Shopbot to cut the 4 pieces out.
Step 1: Design
Inspired by a design by Rachel Gant, I made a variation in Autodesk Inventor.
Each piece was exported as an SAT file for the next step.
