Lego Compatible Disc Buttons
by clothbot, published
How do you make a great idea like Makerbot-printable (clothing) buttons better?
Why, make them Lego Compatible! Naturally.
Update 2009/10/04: In the design files, the knobs are 5mm in diameter. I remeasured my source Lego disc after getting back some Shapeways test prints and the Lego knobs are actually closer to 4.8mm in diameter. I lucked out with my MakerBot-printed buttons; shrinkage brought them down to about 4.9mm in diameter. The Shapeways printed versions are more accurate, 5.00mm diameter, +/- 0.05mm. There's enough give in the plastic materials for them to still fit 'regulation size' lego blocks, but the metal one was simply too wide a diameter.
Update 2009/11/07: I've been playing around with OpenSCAD (http://www.openscad.org/) and came up with the attached DiscButton_20091107 variation. I even added bottom "sockets" to this variation. It's almost too easy when it's all code!

Download the STL. It prints four buttons.
Raft STL in skeinforge
Print resulting gcode.
Ream out holes. I just used a couple of my Makerbot-assembly hex keys.
Sew onto clothing. Use the smaller inner holes for the thread so the larger outer holes remain unobstructed.
