I removed the buckle completely and left the hole all open, while the lid is held down by two effectively invisible pieces of Scotch tape. Yes, it could and should have been done with more finesse. :-) Still that is one decent (while very cheap) enclosure. The plastic is soft but not too flimsy for my liking. The PCB lies on four brass spacers, the additional RF amplifier under it.
