I printed the beehive moat and the rain cover was tight and would not slide on without scraping with an exacto knife.

The changes made in this version are to enlarge the hole for the cover so it goes on easier. Move the small hole in the cover slightly to the center to place it more directly over the moat. Made the rounded surfaces in the moat flush with the flat walls. Increased the screw hole diameter to 4mm. I also made the inside surface where the screw head would make contact with the underside of the top of the moat, flat.

All in all minor changes to a great design.

Print in ABS, 50-100 % fill. Fast resolution is fine.
