About this 3D model

I created this knob for the closet of my daughter. She loves horses. At the back there is a hole to fit a screw in. A diameter of 3.5mm fits excellently. There are small holes around the big hole to assure that there will be enough material to hold the screw even with a low infill. Note: in the picture on the photo there is a letter L in the middle, but this letter is left out in the STL file here. Yes, my daugther's name starts with an L.
