Likely Solved! Small plastic knob, green, ~11/32” (between 8mm & 9mm) diameter, fluted with small male threaded end. Found while picking up my brass casings at an indoor firearm range.
Visual description: First photograph is an image of a small green plastic knob on a cut piece of spruce, facing the "front" of the knob. Second photograph showing the same green plastic knob, mostly sideways, showing the fluted section as well as the shorter threaded section, also on the end grain of a cut piece of spruce wood. Third photograph showing the same green plastic knob sideways in front of a US.Customary System wooden ruler with the left side of the knob at the number three mark and the right side between 5/16" and 3/8", also on the end grain of a cut piece of spruce wood.
