This is my direct drive extruder "V10 JGR Extruder"
changes from the last version:

• hotend mount is now a very rigid , and easier to install and center a hotend
• filament path is shorter
• motor sits on the carriage
• proper idler bearing, no more hunting for artline pen springs
  this extruder will mount the Aluhotend and the jhead
