These are experiments in 3D-printing fridge magnets for our hackerspace. Check it out:

• Hack The Planet
• Mesh The Planet
• Sudo
• Heart
• Double Union
• Anti-Surveillance
• ABOLISH
• Transgender Symbol

Fridge magnets are useful objects, great conversation pieces, and good advertising since people look at them every day!

The model has a hole for one of these. The printer pauses while you insert it by hand. It also moves the bed, which hopefully will make a loud distinctive noise to alert you.

Almost everything is in the compile.sh scripts:

• openscad command to compile an STL
• slic3r command with the exact options we use
• awk command to insert the gcode pause

Right now the scripts also do non-portable stuff like edit my PATH and fix the tempurature for our particular plastic. Sorry, I'll fix it eventually.

The world map is from Wikipedia. I prepared images and text in the Inkscape GUI. Someday I'd like to script this with Python and have entirely deterministic magnets.
