Here’s a really quick 3D model of BlinkM, if anyone needs it. It’s accurate to ~0.1mm.
- blinkm.skp — BlinkM SketchUp model
- rgb_led_piranha.skp — Piranha RGB LED SketchUp model
And here it is plugged into the awesomely done Arduino Diecimila model by Jon-Paul from the Google 3D Warehouse.
SketchUp is pretty great, but I found a problem with it if you’re trying to make accurate to-scale electronic parts: it won’t create surfaces with an area of <1mm. Took me a while to figure that out. The solution is to make a 10x or 100x size version and then do a scale by 0.1 or 0.01 when you’re done.
