thingiverse

Update 5-7: Lever arms updated. Update 12-18: Adjusted lever arm design so two units can fit side by side without requiring sanding. This modification is still untested. Additional features have been incorporated, including a flipped lever arm and an SKP file. My favorite extruder, expertly designed by the all-powerful Misan, has been updated to accommodate an E3D Chimera on my I3 3D printer. It's now ready for flexible filament!
