Wireframed dodecahedron

Sometimes I want to fabricate things that are larger than the build volume on my 3D printer or to make things that are hollow and can be covered with fabric to diffuse LEDs inside. To help out with that, I’ve written a program that will generate 3D printable versions of just the vertices — the resulting object looks like a real-world wireframe of the STL file. This also lets you use other materials for the edges, like wooden dowels, laser-cut acrylic or aluminum extrusion, and makes it easy to cover with stretchy fabric.

The wireframe program parses the STL file, finds all of the unique vertices, eliminates coplanar edges and generates connectors for the ones that remain. It isn’t very smart about some of the intersections of very acute angles, and the output OpenSCAD file needs some cleaning up before it is ready for printing, but simple low-poly shapes can be fabricated without too much effort.

More info is at trmm.net/Wireframe and the source is available. I’ve also posted the dodecahedron that you can make with regular unsharpened pencils from the office supply closet: thing:653464 on thingiverse. I hope you have fun making large-scale things!

  1. Can be great use for plants and vine that can grow wild on it http://www.3dprintingpartner.com
