13 useful 3D printing builds

The glaring, legitimate criticism of 3D printing technology is that, in its current state, it can only print "soft" parts, which largely limits it to things like figurines, mockups, models, etc. However, though the niche for useful 3D printed parts is tight, there are some genuinely useful builds.

Here's a collection of useful 3D printed stuff. Too useful? Then check out PancakeBot.
