⚠️ WARNING: Regarding the Raspberry Pi shortage
The V-Core 3 requires a Raspberry Pi if you wish to use RatOS. However, due to the worldwide semiconductor shortage, availability of these can vary on a day-to-day basis. The store pages for the V-Core 3 kits now include a customizable option allowing purchase of a Raspberry Pi if required, and if they are currently in stock.If the Raspberry Pi you wish to purchase is not currently in stock, the Raspberry Pi Locator website can be of great assistance in sourcing one in your country.
V-Core 3.1 CAD
CAD models for all V-Core 3.1 sizes are made available via the Rat Rig Fusion 360 online viewer. Choose a model to enable the download button below.

BOM
Bellow you will find the BOM spreadsheet for the V-Core 3.1 non enclosed. Beware of the machine sizes as components like extrusions, linear rails and lead screws vary greatly in length. The base parts kit is the same regardless of the build size.

Printed parts
A single archive containing STL files for all printed parts can be found by clicking here. 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.The following table shows the recommended print settings when printing any of the parts provided.

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.

Enclosure Panels
Due to the large number of combinations, individual enclosure panel files are available on the V-Core 3.1 GitHub repository
