Back in 2012, Tony Buser created a Hilbert Cube for 3D printing with PVA water soluble support material.

While looking for new interesting things to print using water soluble PVA support, I decided I want to try to make a Hilbert Cube:

After trying and failing to do it in openscad, I worked around it’s limitations by writing a ruby script that generates openscad code. This ruby script can create a 1-3 iterations of a hilbert curve in 3d. I borrowed code from a Processing script by Thomas Diewald at

In our recent Crickit Lab Shaker project I 3D printed a few of these cubes to demonstrate how well agitating parts with PVA supports works. It’s a really great model for testing PVA support material, big props to Tony! Experimenting with agitating PVA supports for faster dissolving using a DIY lab shaker. Autogenerated supports using CURA 3.4.X. Printed with an Ultimaker 3 using 0.4 BB printcore for Ultimaker’s PVA. More details can be found in the project learn guide:

See timelapse of PVA dissolving in the youtubes

We also have a guide on 3D printing PVA support material

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
