Z axis coupler

This mechanical part is specifically designed for linking a standard stepper motor's 5mm shaft directly to an 8mm shaft on another component. Originally created with 3D printing in mind, this mechanical piece can be adapted for use in numerous other applications. To achieve optimal results, print the design using a high extrusion multiplier of at least 1 or preferably 1.03 to ensure strong bonding between layers. For added stability and durability, I recommend setting the perimeter to three and infill to 25%.
