About this 3D model

We all know that LEGO pieces break sometimes. If you have small children, they may break it very often. Thankfully, we have 3D printing at home now. So it takes only 30 minutes from holding a broken LEGO piece until you can give your child a new one. We've done four pieces in four minutes on our RepRap printer.
