Proteins
In RepRap jargon, a vitamin is anything that you need to make a RepRap, which a RepRap can make itself.
All parts were designes using OpenScad, they are reutilized parts from the Prusa 2 and Prusa i3 box. Font files available at:Josef Prusa's repository
STL files are available at:GitHub
Almost all the structure is made of steel so you will only need th following printed parts:

Vitamins
In RepRap jargon, a vitamin (also called an "imported part" or "non-printed part") is anything that you need to make a RepRap, which a RepRap cannot itself make.
