Bill of Materials - BOM
Below is the BOM spreadsheet for the Stronghold Pro. Pay close attention to machine sizes, as components such as extrusions, linear rails, and lead screws vary significantly in length. The base parts kit remains the same for all build sizes.
Official BOMPrinted parts
All files are provided in the correct orientation for printing on a standard FDM 3D printer. In general, the printed parts are quite forgiving but are also quite large. If you suffer from drafts and/or poor bed adhesion you may need to use brims/rafts for some parts to prevent warping.
Induvidual STLs are available on GitHub
The following table shows the recommended print settings when printing any of the parts provided.
Print Settings:
- Perimeters
- 4
- Line Width
- 0.45mm
- Layer height
- 0.2 - 0.3 mm
- Infill
- 25%
- Supports
- None
When slicing the files you will notice that some of the holes are covered. This is intentional, to simplify the printing process - those layers are there to trick the slicer into building a bridge there. Once printed those need to be poked out with a screw, screwdriver, Allen key or even a matching size screw.
