Proteins
Almost all the structure is made of steel so you will only need the following printed parts:
Part | Quantity |
---|---|
Endstop Holder | 3 to 6 |
X-Axis Motor end | 1 |
X-Axis idler end | 1 |
X carriage | 1 |
Y belt holder | 1 |
Extruder (*1) | 1 |
(*1): Made of several plastic parts that depend on the chosen extruder model.
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.

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.
