Open the .SCAD file with OpenSCAD

Once loaded, render the cube by pressing f6

Rendering may take upwards of 1-2 hours. If you have a slow computer, I would recommend running this overnight.  

The rendering progress bar will appear "Stuck" at 999/1000 for a very long time. Be patient, this portion of the rendering process takes the most time. 

After rendering is finished, export and save the cube as a .STL file

Note: This design is best suited for SLA printing. Use FDM or SLS at your own risk*

Open the STL file in the slicer of your choice

The cube should print at its default size or larger. Shrinking the cube may result in print failure.

(For Resin Printing) Orient the cube at 45 degrees in X and Y, so that it is standing on a corner

Support the cube by manually adding supports running along the thicker outer borders, ensuring that the three edges facing the build plate are fully supported.

Print and post-process your cube

*This design has been validated to print on the following printers: Formlabs Form 4, Formlabs Fuse 1+

The QR code is best viewed in outdoors in direct sunlight, with the shadow cast on a smooth, light surface

The QR code can be difficult to align properly - If you have trouble, start by moving the cube until the shadow is square-shaped, then make small adjustments until a QR code appears in the shadow

Each pair of opposing faces will generate a unique QR code
