The Work Sharp Precision Adjust has nowhere to store the sharpening stones and rod. I created this model to do that, as well as make the base bigger and therefore more stable. My sharpener snapped in and is held snugly. Originally, I planned for a looser fit and would have used hot glue to hold it in place. I also uploaded a second model that will hold up to three sharpening rods if you have bought the accessories. You can see it on the second  plate in Bambu Studio.
