About
Hi, I'm Jeremy.
I like to 3D print things and build software. I write down how, so you can build them too.
beetlebug.org is where I put my open hardware and software projects. Most of the hardware is 3D printed and designed in code (OpenSCAD, build123d, or FreeCAD), so every dimension is a named value you can change.
Each build guide has a parts list with links to sellers for each part, the print settings I use, and an interactive exploded view for every step. Drag the model to turn it, and scroll the steps to watch it come together.
