Potentiometer Knob D Shaft Remix

Found that the original was a little too thick for my fingers to fit between when installed on my Electribe Ea-1.

Made this one a little thinner. Maybe a little slippery to grasp, but at least it leaves space.

I found TPU/TPE can be a little more gippy

Oh and there was a random cube/rectangle in the original design that is too small to print but would cause problems if it did, so I deleted it.
