B-Struder - E3D Hobb-goblin edition

thingiverse

So I came across the original B-Struder while searching for extruders. I like the design, but as I had some E3D Hobb-goblin drive gears, decided to remix the design to support those. Changes to original: - basically the arm was re-designed from scratch in OpenSCAD to match Hobb-goblin gear - the arm's filament path needs to be drilled open. See post-printing - other parts (MR105zz_support, lock lever) extended in height as needed - extended and added some bolt holes to the motor mount as I needed those for my own use (4mm hole, 29mm distance) - lock lever has other 'arm' which should help operating it. I actually cannot use it due to space constraints (was a good idea but didn't check clearances...) - added a spacer which can be used if one has MR105zz_support and lock lever from original thing - added new spring cap for 8mm spring Most of the original instructions and part list apply. You will need a bit longer than 25mm M3 bolts for this. Also I'm not using the printed washers but those should fit fine.
