Extruder Loop

this is an extruder named Loop:

  • for NEMA17 stepped motor
  • standart 50mm M4 fixation holes at the bottom
  • RichRap quick-fit compatible
  • J-head/e3d nozzle buit-in holder

it's mainly a variant of http://www.thingiverse.com/thing:28916 and Greg's Wade reloaded
what is different then?

  • Tiltable M4 idler-screws really open (by 40°) and have a stronger nuts housing
  • filament is closer to the M8 drive bolt than olekdh version (3.7mm center-to-center)
  • oblong hole for motor positionning are wider, allowing to disangage the gear for easier assembly
  • add a support for drive screw bearing surface.
  • it's fully redesigned in Solidworks 2013
