Prevents the laser cable and optional Air Assist hose from rubbing against the top of your enclosure if you use the xTool risers (or my designed honeycomb centers & risers). Or just to keep them out of the way… Perfect and tested fit on the IR and 20W (5W or 10W unknown as I don't own these, so you'll just have to try it out). You need to replace the 2 x m3 bolts currently on the top back side of the laser with slightly longer ones (30mm works).
