Hi! My name's William and this is my first time on instructable.com
My first project is this Lego Mindstorms 3D printer. I've already built a prototype before this version, but the results were well...mediocre. This is the 2.0 version. It's more precise, more efficient and the printed objects are better than in the previous version, although far from perfection.
- 2 large (16x32) lego plates
- About 30 Lego gear racks (4x1)
- Long and thin Lego bricks
I think that the image explains pretty well how to build the X and Y axis so I hope you won't need any further information for this step.
