SmartrapCore 1.0 modified Simplex extruder (for Nema 17 & Bowden) V. 0.5

thingiverse

I adapted my own version of the Simplex extruder (http://www.thingiverse.com/thing:91054), which comes pre-installed on the prototype of the SmartrapCore printer, paired with a Bowden and a Nema17 stepper motor. This was an easy tweak, but necessary adjustments include: Smaller dimensions (I wanted to save some PLA). Since the insertion hole for the filament is positioned at the bottom on the Bowden model, I enhanced this opening (by creating a clear border and conical shape) to make it easier to load the filament.
