P3Steel Bill of materials
Contents
Proteins
The P3Steel requires a considerably smaller subset of printed parts compared to the Prusa i3:
| Part | Quantity |
|---|---|
| Endstop Holders (*1) | 3 |
| X-Axis Motor end | 1 |
| X-Axis idler end | 1 |
| X carriage | 1 |
| Y belt holder | 1 |
| Extruder (*2) | 1 |
(*1): These may be all identical or different for each of the X, Y and Z-axis.
(*2): Made of several plastic parts that depend on the chosen extruder model.
See the P3Steel Proteins page for the recommended printed part designs.
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. See the P3Steel Vitamins page for details.

Rods
Threaded rods
Only 2 M5 threaded rods are needed:
- 2x Threaded rod M5x295 mm
Smooth rods
6 Stainless steel 8mm smooth rods (optionally chromed) are needed of the following sizes:
- 2x Ø8x375 mm for the X-Axis. (385mm for version 2.5)
- 2x Ø8x341 mm for the Y-Axis (350mm for versions 2.01 and 2.5 of the frame).
- 2x Ø8x320 mm for the Z-Axis. (330mm for version 2.5)
Screws, nuts and washers
The entire steel structure is assembled with approximately 40 x 12mm M3 hex screws and the corresponding M3 nyloc nuts.
A few more M3 hex screws are required for the steppers, 2 x M5 nuts are required for the Z-axis threaded rods and some more screws, nuts and washers of various sizes are required depending on the choice of extruder, X motor mount, X and Y idlers and endstops.
See the P3Steel Vitamins page for a more detailed list of screws, nuts and washers needed to assemble a P3Steel.
