Potentiometer Knob with arrow

updated the insides for a snug fit on my compressor Potentiometers ( DBX 166 XL ).
added arrow.
there are 2 different insides,
one face up - one face down.

i printed right side up to preserve the arrow on top. and just did 2% support for the inside. support popped out nice and clean. fit was good for mine. but they all seem to be a bit different.
