While we're all for 3D printing, it can sometimes be a huge mess. The ink oozes incorrectly, creating a blob out of something you painstakingly designed. You can always invest in MakerBot, which tracks your 3D prints in real time, or you can go the route of designer Bernat Cuni, and embrace your 3D fails.
Cuni made a book of the pretty almost-objects designed and created on his 3D printer. It's called Beautiful Failures, which is very apt title. Check out some of his more spectacular breakdowns below:
Almost a bunny
Kind of a star
A lovely... thing
And my personal favorite...almost a teddy bear
