Extruder Loop

thingiverse

Loop is a NEMA17 stepped motor extruder with standard 50mm M4 fixation holes at the bottom, RichRap quick-fit compatibility and J-head/e3d nozzle built-in holder. It is largely based on http://www.thingiverse.com/thing:28916 and Greg's Wade Reloaded designs but features several improvements. The tiltable M4 idler-screws can now open by 40° and have stronger nut housing, the filament distance to the M8 drive bolt is reduced to 3.7mm, oblong holes for motor positioning are wider for easier assembly disengagement, and there's added support for drive screw bearing surface. The entire design has been fully redesigned in Solidworks 2013. For more information and a changelog, refer to the instructions. Print extruder_Loop_v1.1.stl, J-head_caps_for_extruder_Loopv1.1.stl, biggearmod_fixed.stl, smallgearmod_fixed.stl and jonaskuehling_gregs-wade-v3_idler-only.stl from http://www.thingiverse.com/thing:18379. Assemble mechanical parts (instructions provided) and refer to the changelog for v1.1 updates, which include increased tiltable idler-screws angle, wider holes for idler-screws, increased clearance for door support basisi, increased space between filament hole and drive bolt, and reduced quick-fit plugable ends height.
