The new Rat Rig Toolheads are the result of painstaking testing and design iteration to achieve optimal printing performance. With a rigid, light and compact metal body, they use only a few printed parts which are supplied in ABS, to withstand the high temperatures of an enclosed printer. STLs for optional toolboard mounts are also available.

This page will guide you through the easiest upgrade to elevate the performance of the V-Core 3.1 to the next level. 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.
