Summary

This model demonstrates a means of folding rigid, thick panels into a compact, near-cubic form. The design is based on Dr. Robert J. Lang's recent publication: "Squaring the Cube: Efficiently Stowed Deployable Mechanisms With Thick Rectangular Payload Panels". Also, this model needs to be printed flat side down! You should not need any supports for this one.

Printing Instructions

This model needs to be printed at 0.1mm layer height (any typical nozzle diameter should be fine) and should be printed with a 60 degree infill direction, and a 120 degree bridge direction. This gives your hinges the best shot at being strong during repeated folding.

Here's a short video example of how to bias the hinges:
