After having issues with direct drive extruders on my Rostock I wanted to go back to my old faithful Wades extruder. This bracket will allow you to turn a standard "J-Head" Gregs or Wades extruder in a Bowden arrangement. The hole at the top will take a 1/8" BSP Male to 6mm push fit pneumatic fitting and the two encapsulated nuts allow you to build the extruder before mounting to the printer. Note: It now looks like my direct drive issues were with the stepper driver not the extruder :-(
