P3Steel Proteins

Proteins
In RepRap jargon, a Protein 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 allows 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.

X-Axis motor end
This part holds the X-Axis motor, fastens the Smooth rods of the X-Axis, holds two LM8UU bearings for the left Z-Axis smooth rod and the nut for the left Z-Axis threaded bar.
Different X-Axis motor ends can be fitted to the P3Steel printer. Here we list some options.

X-Axis idler end
This part holds the X-Axis idler, fastens the Smooth rods of the X-Axis, holds two LM8UU bearings for the right Z-Axis smooth rod and the nut for the right Z-Axis threaded bar.
Different X-Axis idler ends can be fitted to the P3Steel printer. Here we list some options.

X-Axis carriage
The moving part of the X-Axis, I'ts binded to the X-motor by a timing belt and slides from left to right carrying the extruder and hot end.
Different X-Axis carriages can be fitted to the P3Steel printer. Here we list some options.

Y-Axis belt holder
This part goes attached to the bottom of the Y-Axis carriage, I'ts bonded to the Y-motor by a timing belt allowing the Y-Axis carriage to slide front to back carrying the build platform (heated bed).
The design of the P3Steel printer includes an steel part to serve as Y-Axis belt holder but plastic belt holders can be fitted too. Here we list some options.

Extruder
Different extruders can be fitted to the P3Steel printer. Some fit straight and some need especial X-Carriages or adaptation. The chosen extruder will require specific Vitamins so you should have clear what hot end will be used, then choose the correct extruder variant and then its vitamins (motors, bearings, hobbed bolt/pulley,etc)
Some extruder examples listed.
