Triple Bowden Rubberband Extruder Drive for Tri-colour

NOTE: This uses a Makerbot MK8 hobbed bolt/drive gear

This extruder unit is for a bowden system with three extruder drives. A screw hole has been added to make it easy to attach this to your Vslot system using a M6 screw.

This system features three M6 tube connectors as shown, to attach your bowden tube. This will be attached to your hotend on the X-carriage. The M6 pneumatic tube connectors can be screwed into the holes directly without the use of any nuts.

This system is based upon my original Rubberband Extruder design

Please note that the original design features a MK7 Hobbed bolt, this system has been adapted to use the MK8 hobbed bolt.
