The downloadable model was normalized at 25.4× based on inferred inch units. Import it at 100% as millimeters and confirm the dimensions in your slicer before printing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFit and test disclosure:\u003c\/strong\u003e the loop is approximately 3.41 mm across the outside with an approximately 0.77 mm radial wall and 3.81 mm height. Standard key-ring fit, support needs, real-world durability, and printer-specific results have not been physically verified. The model has not yet been test-printed.\u003c\/p\u003e\u003cp\u003eThe broad flat cover at Z=0 is the candidate build-plate orientation. Suggested starting points are a 0.4 mm nozzle, 0.16–0.20 mm layers, three walls, four or more top and bottom layers, 15–25% infill, and PLA or PETG. Inspect the sliced preview and adjust for your machine and material.\u003c\/p\u003e\u003cp\u003eSales are currently paused.
