Non-metallic alignment tool
thingiverse
This is a non-metallic alignment tool, aka "tweaker", aka "diddle stick." One end is a flat blade for adjusting trimmer capacitors, the other is a hexagon for adjusting tuning coils. Hex shape keeps it from rolling off your workbench. Instructions Print with support enabled. You may or may not need cooling too. I recommend quickly printing the short version in the stl file first (print is 15 mm. long), to make sure the dimensions come out right on your printer. You can then easily tweak (or diddle) the length you want in the scad file.
