ELFA-Compatible Corner Bumper

After my partner nearly beaned herself on a protruding corner, I designed this to soften the blow from solid ELFA shelving. These should fit any 3/4" Melamine shelves. The tolerance is close enough that they stay on the corners without any additional adhesive.

They print upright with supports, but the interior angle is minimal enough that the support is really just for the little notches on the sides.
