Product Details
RatRig Socket Screw Kit
RatRig Socket Screw Kit for the V-Core 3 series of DIY 3D Printers, all versions. Because of continuous evolving updates, this kit is a combination of both the V-Core 3 and V-Core 3.1 official BOM. Detailed list below. Kit also includes spare screws.
FIY: Screws for the Eva 3 are not included with the BOM but we have a kit available here which will apply to any configuration you choose. It is available in both nuts and heat insert versions.
Also: M6 common flat washers (36) are required. We currently do not offer them in any of our kits since they are easily sourced locally.
