thingiverse

Here is the rewritten text in American English: Dual-extrusion enabled model holds two Ubis extruders for parallel production. Instructions: Disconnect existing aluminum extruder, swapping it with this updated model. Position Ubis extruder below, secure with screws; if the extruder won't fit, tape around it for a snugger fit. Screw on a push-fitting at the top and voila - a simple Bowden extruder is created. Interface secondary stepper controller to RAMPS board or Extrudrboard, wire and set distance to Y+26mm. Ensure identical Z height for both extruders and experience dual-head printing with ease.
