The EggBot project is an open-source hardware+software project compliant with the Open Source Hardware Definition.

  • EggBot code is hosted at GitHub.

For the rest, you can download the Egg-bot hardware reference design here (900 kB .zip archive).

The reference design includes the following files:

  • Bill of materials, CSV format
  • 1/4" plywood pen-arm parts, Inkscape SVG
  • 1/4" Poplar pen-arm part, Inkscape SVG
  • 0.020" delrin part, Inkscape SVG
  • 0.010" acetal copolymer, Inkscape SVG
  • Eggbot chassis "acrylic" reference design, Inkscape SVG
  • Eggbot chassis original design, gEDA/PCB
  • Precision Egg Coupler design (Solidworks/PDF with readme)
  • Aluminum Pen Arm Backer design (Solidworks/PDF with readme)

The wood and plastic parts can be cut by standard laser-cutting processes, or other machine tools at your discretion. The Egg-Bot production chassis is made from fiberglass in a PCB process; a reference version is also provided in case you would like to make one from laser-cut acrylic (or other materials) instead. The two machined parts (Precision Egg Coupler and Aluminum Pen Arm Backer) are optional replacements for the versions in the base design.

The EggBot was designed in Inkscape, with assistance from gEDA/PCB.
