printrbotGO and a Companion Cube. Click for larger version

I just can’t stop building portable 3D printers! Check out my new printrbotGO – an all new design in collaboration with

The goal here was to create an interesting, functional, sturdy design and then have it be available pre-built or as a kit. This is the first prototype and will be demonstrated at World Maker Faire New York weekend of September 28th – 30th.


  • Printrboard electronics, steppers, pulleys, extruders and hot ends (all existing commodity parts from one source)
  • Print size 200mm x 185mm x 150mm. Not sure why I lost that 15mm on the Y axis, will probably have that at 200 as well in the future.
  • Runs off a wall wart power brick or internal Li-Polymer batteries. We estimate 2 hours print time in PLA.
  • Folds up to a size of 19″ x 14.5″ x 5.5″ – can fit in a plane’s overhead bin.
  • Much smaller “deployed” footprint than my previous models.

Android devices: MINIX NEO X7 and MINIX X7 mini

For the latest episode of the Ben Heck show we built a retro-style case for the Raspberry Pi single board computer.

Features include:

  • Power switch and standard barrel power plug / wall wart.
  • Card-edge connector (cartridge slot) for easy general purpose I/O breakout.
  • Custom PCB’s for experimentation and learning.
  • Hinged keyboard allowing easy access to internals and storage for experimentation parts.
