If you own a Slonik headlamp like mine that has a snap in mount with a tab to secure the adjustable angle this model is something I spun up taking inspiration from some other designs I've seen for this same model but adding a bit of built in support to ensure the small cantilever for the tab in the middle prints cleanly without supports.

The best way to print this is vertically to avoid any cracking at the layer lines when you take the lamp in and out of its holder. I suggest doing manual support painting on only the top cantilever. In my version I also had the support interface do an ironing pass and .1mm distance between interface and the print to attempt to improve the bottom surface print quality.

The .STL should be oriented correctly be default, however just make sure the built in cantilever support on the middle tab is the printed first in order to support the cantilever, its not needed for the top bridges.
