P3Steel 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.

Lasecut parts
P3Steel frame is mainly built from lasercut steel. CAD Drawings are available from GitHub and author's page on Thingiverse.

Mechanical Parts
Bearings
Motors & couplings
Rods
Threaded rods
Only 2 M5 threaded rods are needed:
- 2x Threaded rod M5x295 mm
Smooth rods
6 Smooth rods are needed of the following sizes:
- 2x Ø8x375 mm for X-Axis
- 2x Ø8x341 mm for Y-Axis (350mm for version 2.01)
- 2x Ø8x320 mm for Z-Axis
Screws
Approximately (with a reasonable safety margin):
80 x M3 nyloc nuts.
60 x M3 12mm bolts. 20 x M3 20mm bolts. 20 x M3 8mm bolts.
20 x M3 washers.
2 x M8 30mm bolts. 2 x M8 nyloc nuts. 10 x M8 washers.
The above does not include the screws, washers and nuts needed by the extruder. Stainless steel (vs. mild steel or carbon steel) M3 screws and nuts are much preferable, mainly for the frame assembly.
