Solid coupling
thingiverse
Rewritten text: This parametric solid coupling allows adjustment of bore positions via the openscad file and grub screw size customization. It's ideal for connecting stepper motors to rods of different sizes, or any rods with varying dimensions. To use, modify the solid-coupling-grub.scad file, print it (30% infill, 0.3mm layers), and slice with SFACT or Slic3r. Compiled objects are available to couple a 6mm shaft to an 8mm one, as well as a stepper 5mm shaft to a 1/4" shaft. For large shaft sizes, adjust the grub screw hole using setscrew_offset variable. The shaft holes have built-in 0.1mm clearance, adjustable if needed. Note that this requires myLibs.scad library for additional functionalities.
