I built mine from a storage tote this time, the wooden one from last year is heavy!
 
Be sure you use a fresh, sharp blade to cut the center out of a plastic lid! Score it like 4 times before trying to cut it so you don't crack it. The plastic type on mine was really hard.
 
We used a drill for the holes, cut the hardware cloth to size, bolted it on with washers on the nut side to secure the hardware cloth. So easy to clean!
 
The hardware cloth is under the edge of the lid, to avoid crud getting stuck between wire/plastic on top. The bolt heads are on top, the rest of the hardware below.
 
Seriously took all of like 10 minutes to alter the lid on the tote.
