Rat Rig V-Core 4 Idex upgrade

Unleash endless possibilities!

The new Rat Rig V-Core 4 IDEX is the result of painstaking testing and design iteration by Rat Rig and its community. The IDEX (Independent Dual Extrusion)  introduces a second tool head, enabling you to reduce print times and print with multiple materials.

Let's go...

This page will guide you through all the specific idex content. Below, you will find the CAD, the bill of materials (BOM), the repository of printed components featuring all the STL files, and a comprehensive, step-by-step assembly guide.

Why idex?

While the V-Core 4 is a beast on its own, the IDEX takes it to the next level, unlocking a new realm of possibilities. It offers everything from multi-material capabilities to doubling production capacity, all while ensuring that every user can easily harness its potential with a semi-automatic and intuitive calibration process.

Unparalleled speed

Upgrade BOM

Below is the Bill of Materials (BOM) spreadsheet for the Rat Rig V-Core 4, including all components necessary for the IDEX setup.

Upgrade Printed Parts

Check our github to get access to STL files for all printed 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.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.
