About this 3D model

Threaded knob that fits 1/4-20 threads. Off of my printer, these knobs thread on easily and fit well. Print flat side down. If the threads don't fit well, scale up or down in the x and y axes, but not z, to maintain 20 threads per inch. Threaded bit is 3/4 inch long (19ish mm). Overall length is 2 inches (51ish mm). Knob diameter is 1-1/4 inches (32ish mm). Printed on a Creality CR6-SE at .16mm layer height and 40% infill. Could probably use less infill and still be plenty strong. Threads off of the printer are surprisingly accurate.
