We're excited and proud to launch Thingiverse Apps. Learn More about what this means to you.
The attached OpenSCAD script allows you to create trip-let blocks: shapes whose projections along the x-, y-, and z-axes can be completely different. Probably the most famous trip-lets appear on the cover of Douglas Hofstadter's book GÃ¶del, Escher, Bach: An Eternal Golden Braid.
Instructions on how to customize the trip-let produced can be found in the comments of trip-let.scad. The script is very basic. Most notably, it does not detect whether the created trip-let actually has the desired projections or even whether the block is in one piece. You will probably have to experiment with various rotation settings before you find a workable trip-let.
A couple of example trip-lets from the script (including an approximation of one from the cover of GEB) have been attached in STL format. You'll need to scale and translate the model appropriately before printing.

So what's this mean?
We're sure zec would love to see what you've printed - take a photo and share it on Thingiverse as a Make.
To post a Make simply visit this Thing again and click I Made One to start uploading your photo. You can also download the Thingiverse Mobile app (available via Google Play and Apple App Store) to take a photo and upload your Make right from the app!
