A retro cabinet door knob. Hole = 3.7 x 14 mm.
Size 50 x 35 mm. Downscale to 95% (version 1)
Turn it upside down before printing. (version 1)

Edit: The knob's slim leg seams to be fragile and breaks easy, especially when used on a heavy drawer. I added a second version, which can be attached with a 2 inch/45-50mm; length depending on the door thickness (#7/#8, 4/4.5mm.) wood screw, stucked in the sphere instead of the weak leg.
