drill press handle knob

This is a remix as noted. The original was just what I was looking for to replace the knobs on my drill press. The only thing I changed was the hole for the handles. The handles on my drill press are threaded 3/8 16 UNC and requires a tap drill size of 5/16" (9.52MM). The original has a hole diameter of approximately 3/8" so I took the original design, using 3D Builder (windows 10) and inserted a hollow cylinder with the correct size hole then after printing, just ran a 3/8 16 UNC tap down the hole the same length as the threaded part of the handle and all is good. Perfect fit and size.
