All bottom-side components must be less than 0.25” in height so they don’t touch the inside of the bottom cover. You can fold parts over, but I would never, ever attempt to modify their height by removing material. If you feel compelled to do that, better to just request a lower-profile replacement lower profile part from Elecraft.
