Drawer Knob in Art Deco style.
It has a small hole to make it easier to insert a screw, but you might want to change the sizing depending on the screw you're using (I've included the STEP/F3D files), or just use a drill.
I printed it pointing upwards with supports under it. Just make sure to suppress supports on the screw hole. I also recommend using ironing as it would make the top look much better since it has small details that are hard to fill with a 0.4mm or larger nozzle.
