BCN3D++B Single Bowden extruder

thingiverse

This remix showcases my refinements of the DaniSaez Remix (http://www.thingiverse.com/thing:419278) of my custom Bowden extruder for BCN3D+ machines. Dani deserves recognition for streamlining the carriage width, but to make way for the fan at the front of the device, it was relocated from its original position. As someone who enthusiastically monitors print jobs (call me driven), I reengineered certain components to move the fan to the rear and achieved a new layout that blends functionality with efficiency.\nI observed an issue raised by Dani; securing the 25mm cooler fan directly onto the carriage with glue may not be ideal, which motivated me to develop an alternative solution involving mechanical fasteners for attachment.\nDrawing on RepRapBCN's proven support design and adapting it for BCNozzle (initial tests suggest I might have secured a minor breakthrough), allowed me to reimagine a few parts within this updated project.\nThe introduction of an additional function for the existing layer fan supports is the heart of my revision; namely, serving as both a fan shroud holder and a mechanism securing the drive belt during printing cycles. The full materials palette drawn from my previous works remains valid here (the relevant pieces may be accessed via those hyperlinks), albeit two new additions have emerged. ABS continues to provide top-tier print results with specific stipulations outlined within, most crucial being ABS usage on key components including fan and carriage sections for best print resolution outcomes achieved using the software of choice, specifically tailored for BCN3D machines (available for direct download in said config file).
