Shy Rockabilly Extruder

thingiverse

The Shy Rockabilly Extruder reinvents the B'Struder universal Bowden extruder, keeping the same foundational concepts but empowering users to modify model specifics like filament thickness and bearing particulars through parametric tweaks. This revamped design features a reduced extruder arm profile requiring only two bearings instead of three. Like its original counterpart, the Shy Rockabilly Extruder relies on 623 bearings, necessitating only two for seamless functionality. M3 nuts and screws assemble everything neatly. Designed with a Mk8 drive gear and an M5 threaded tube connector in mind, adding a 10mm diameter spring ensures arm tension. Printing various iterations using ABS and PLA filaments shows moderate infill performance. The extruder face can be printed as is without any adjustments. The arm can either be printed upside down without supports or in the traditional orientation with support features enabled; albeit printing the bearing enclosures upside down produces messy results, the arm remains functional. My extensive testing demonstrates that this design operates flawlessly on a large kossel-style delta printer. This intricate model was crafted using Autodesk Fusion 360, and original files are readily available for modification via http://a360.co/1OkhVqS and http://a360.co/1It9gq2
