The 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.

While the EVA 3 toolhead is designed for maximal compatibility with a huge variety of extruders, hot-ends and other accessories, the Rat Rig Toolheads are streamlined to be used specifically with our favourite combination: the Rapido Hotend with the Orbiter extruder.

Notes About Holes:
When slicing the files, some holes may appear covered.
This is intentional to help the slicer create bridges and simplify the printing process.
After printing, clear the holes using a screw, screwdriver, Allen key, or matching-size bolt.
