The Baltimore Node is pleased to have taken part in the creation of the cover for Urbanite Magazine’s March 2012 “Change Makers” issue.

The file was designed in Inkscape and OpenSCAD and printed on MakerBot Thing-O-Matic #5564. Dozens of photos were taken during the build and then combined into the final cover image by the excellent people at Urbanite.

You can find the online archive for the issue here:

Print and enjoy.

If you print it upright (as we did, for time-lapse purposes), you’ll likely get some stringing.

Change is messy. :)

This object was made by:

  1. Creating text and baseline shape in Inkscape and combing it all into a single path.
  2. Exporting the path to OpenSCAD polygons using this Inkscape plugin:
  3. Adding a call to “linear_extrude(..)” in the resulting OpenSCAD file.

To go with the new multiple-color plotting functionality of my Unicorn G-Code Output extension for Inkscape, here’s a new version of the Baltimore Node logo.

This one is ready to plot in 2 layers - all of the black parts at once, followed by all of the blue ones, with a pause at the beginning of each layer to allow a pen change.

I also made use of my Hershey Fonts in SVG to make the word “baltimore” more readable after plotting. This should make it look nice, for example, on an EggBot.


I forgot to resize the original for a sticky note pad (whoops!) and I was right that the EggBot version needed layers beginning with a number.

Updated files attached and pictures added!


If you have a Unicorn, try out the attached G-Code. It’s set to start with the pen centered over 0,0 and fits on a sticky note pad (75mm x 75mm).

If you have an EggBot, try plotting the SVG using the Layers dialog. Layer 1 is black, Layer 2 is blue.

I felt that it was about time Baltimore Node had a Unicorn-plottable logo! You can learn more about this awesome hackerspace at

I’ve attached all the files I used to create the G-Code for this thing, which tells the story of how you can make your own:

  • node_logo.svg - Start with the SVG logo available from the Node wiki.

  • node_logo.eps - Use Inkscape to export an EPS file, making sure to convert text to paths.

  • node_logo.dxf - Use pstoedit as described on Tony’s 2D-to-3D post - - to create a DXF, with simple line approximations of curves. I also ended up using some scaling:

    pstoedit -xscale 18 -yscale 18 -dt -f dxf:-polyaslines node_logo.eps node_logo.dxf
  • node_logo.gcode - Use from GitHub to convert the DXF into Unicorn G-Code.

I used Pleasant3D for its excellent G-Code preview capabilities to check that everything looked reasonable, find a good scaling, etc.


  1. Load node_logo.gcode up in ReplicatorG
  2. Line up your pen as shown in this image:
  3. Build!

You may need to flip axes, etc.

I also don’t have any of the niceties like pen registration tests or multi-sheet printing in this G-Code. Feel free to add your own!
