Proteins

In RepRap jargon, a vitamin is anything that you need to make a RepRap, which a RepRap can make itself.

Most parts were designed 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:

Carriage parts

Endstop holders

This part allow the attachment of the endstops to the frame. You will need 3 for a basic setup (homing axes) and 6 if you want to sense both ends of each axis.

Different endstops can be attached to the P3Steel printer. Here we list some options.
