I've scaled up Steeve Becker's cropped version of David Neff's 123D Catch scan from the Met MakerBot Hackathon to (almost) life-size and sliced it into pieces for the MakerBot Cupcake.
This is my second life-size sculpture print. The whole thing is 38.4cm tall assembled.
Two sets of files are available: One for stock Cupcakes (26 parts, untested), and one for tall Cupcakes like mine (16 parts). (Zydac's Z-axis upgrade at thingiverse.com/thing:4716 is very easy and highly recommended.)
