This insert will let you snug down a knob on the KAD short shifter and clock/align it appropriately. In this case, I'm using a Retro Components knob with the Classic Mini 4-speed shift pattern. Tightening it down without this insert leaves it positioned at an awkward angle.
This should be printed in TPU, so you can compress it to tension the knob to the rod. Print it with the cone facing down with a brim. Infill can be modified to adjust the amount of tension when it's compressed.
