Anet A8 X-Axis Belt Tensioner

Sorry about the subpar picture. I produced this print using PETG filament, and surprisingly, it turned out great despite one minor issue - the part tends to lose its tension rather quickly, albeit still maintaining a fairly stable level of tightness. This seems counterintuitive, as you'd expect the screw to remain firmly in place, but the tiny vibrations likely play a role in this phenomenon.
