Fits a standard Plantronics headset plug/jack with no modification or hardware. It's slightly wider than I'd like in the back, but fits nicely. I have a newer alternative version in the works to upload shortly.
This version has detents only on one side - this seems to be sturdy enough, but it would be trivial to add them to both sides to fit in the screw-holes on the plug.
Print in a standing orientation, wide side (with the detents) at the bottom. Uses about 6 grams of filament, and works very well in PLA+ as long as you don't leave your headset in a hot car for extended periods. Haven't tried PETG or ABS, but should work about as well in those plastics.
Installation is accomplished by pinching the sides in and inserting the plug from the side with the detents until they snap into the screw bore-holes. Pinch and pull off to uninstall. Easy, and takes about 2 seconds flat.
This version, and subsequent ones, are low-res with somewhat pronounced polygonal sides. This doesn't feel bad, or affect use in any way, at least to me or others asked about it, but if rounded sides are desired, I can produce that in the future.
Snowflakes downloaded separately and solvent-welded to the sides for a festive seasonal appearance but can be decorated to taste (snowflakes not included).
Included is a plate for the sides (not pictured) which can be decorated with designs or text (e.g., a controller's operating initials).
