The folks going to the Bay Area Maker Faire 2013 asked how the delta robot fans could find each other. https://groups.google.com/forum/?fromgroups=#!topic/deltabot/U2fU_E9hAT0 Here's one way! A printable badge. It would also be fun to mount to your robot. Several STLs are included, "Deltas Do It Better" and "Delta Robot Fan" and "Viva La Delta". The features are raised so it's easy to color with a sharpie. It's a quick hack, but it's reasonably parameterized - you can adjust the angle of the "model", various model parameters, how much the lettering is raised, the text. Thanks to http://www.thingiverse.com/thing:13347 for his font. There's probably a better to require a font dependency than including it - please let me know. The insets are rendered in layers so the file could be modified such that multiple filament bot would also render it as layers. Note: it's showing up in customizer but the text is disappearing. If anyone knows why this is please let me know. It may have something to do with the fact that the text is from an include file.
