I printed the key using Prusa Slicer on an Artillery Sidewinder X2 with a 0.4mm nozzle. I believe a finer nozzle would yield better results. The inlay was printed with a 0.08mm layer height, while the key body has a variable layer height (0.08mm at the top part where the logo is and 0.2mm for the rest).

The stem is a bit recessed. So you need to support it (but only the base of the stem, not the whole inside).

The key fits perfectly on a Razer Blackwidow keyboard. You can customize and create your own key with OpenSCAD. Check out my repository on Github: https://github.com/nharrer/cherrymx-commodore-keycap
