MakerBot employee Johnathan Cook suggested embedding recycling symbols into the things we print. I think this is a really cool idea.

I was able to take Johnathan's original JPG, trace it into an SVG in Inkscape, export to DXF files for cutting, and then extrude into a printable STL in OpenSCAD. I've attached a file with each of these intermediary filetypes. If someone wanted, they could now add one of these symbols sticking out from their object or cut out from their object to leave this impression.

Each of the STL files indicates the approximate dimensions of the recycling symbol.

This file produces an ABS recycling symbol of approximately 70x90x10mm.

This file produces a PLA recycling symbol of approximately 70x90x10mm.

This file produces a recycling symbol of approximately 70x70x10mm.


  1. Add a blank recycling symbol, an ABS recycling symbol, or a PLA recycling symbol to your printable objects!
  2. Use
  3. Recycle
  4. GOTO 1

I don't see the OpenSCAD file?

Okay - I've uploaded it!

The OpenSCAD is really quite uninteresting. All I did was extrude the DXF files to 10mm and then tried to center them on the XY plane.

Ah! So it does! Well, this at least gives some additional choices.

Great minds think alike. :)
