I've got a cheap webcam that has the world's most useless stand. It just doesn't work at all.
Today I pulled out the calipers, measured the little nub that connects to the stand, and went into sketchup to build this thing: http://www.thingiverse.com/thing:506645
Time to design: about 5 minutes
Time to print: 29 minutes
Got it on my first try, exactly what I wanted. I know it's silly and simple, but wow, is it a rush to design and print a thing you need.
