The "uncomplicator" responds with "just blow them off with a fan".
Be the uncomplictaor.
_edit_: actually I'm the 2nd degree complicator compared to crafish's reply, which is just "cut four rounded slots with an x-acto", no adhesive necessary.
2nd edit: two diagonal slots, one for each corner. Be the uncomplicator.
