A stick lock to avoid damage to the controller's sticks when e.g. carrying it in a bag.
Clamps around the thin shaft of the stick, snapping in place while remaining easy to remove.
Must be printed in a flexible material.
Most likely fits the newer XBox Series controllers as well, but I don't have one available to actually check. Seems to also fit XBox 360 controllers.
In a few weeks I'll be able to test if it fits on a Steam Deck controller stick - will update this description.
In general it's expected to fit around any stick with 9 mm shaft diameter and 4 mm of vertical space between fixed base and top.
