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:
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.

Printer:
FrankedCube
Rafts:
No
Supports:
Yes
Resolution:
0.2mm
Infill:
50%
Filament:
Esun? ABSAny
Notes:
For the arm. 4perimeters and 50% infill. I used supports, but should work without those too if your printer and material like bridging.
The motor mount should be solid. Other parts 2-3 perimeters, 20+% infill.After printing the arm, you need to drill out the filament path with 2mm drill bit. This is by design as I tried to maximize continuous perimeters around the filament path and drive gear hole.
When printing, be careful to print straight! There's a small hole that should guide the drill bit, but the drill bit can still wander if not careful.
The M6 push fittings should be possible to just screw them in. I haven't printed the arm without supports so don't know how well the threads work if printed without supports
