2.5in Inner Diameter Threaded Cabinet Grommet

When I built my resin 3D Printer cabinet to exhaust the fumes from my workshop correctly, I needed holes to run the power cables.

To keep them simple, I created them in two parts, which are threaded for easy installation. Once I drilled the holes in my cabinet, I needed to thread the two halves together to provide a clean edge for the cable to pass through.

Print at a 0.2mm layer height using default settings. No supports required.
