NEMA17 stepper to M6 Thread Rod Solid Coupler by AutoX3D

After growing tired of the numerous other designs I had downloaded, I decided to take matters into my own hands and create this straightforward yet highly effective coupler from scratch. It features a solid, non-flexible design that aligns effortlessly, and its one-piece construction makes installation a breeze, much like the aluminum models I've worked with in the past. To assemble this coupler, you will need two M3x12mm bolts and two M3 nuts. A 0.3mm layer height paired with 15% infill and 2 perimeter settings, along with a honeycomb infill pattern, produces outstanding results.
