Aquarium brace shelf

I needed a place to securely mount my auto-feeder before going on vacation and wasn't happy just velcroing it directly to the tank brace. Threw this together to fit over the brace and then be zip-tied to the brace.

NOTE that those tank braces are structural and not meant to be weight-bearing!! I'm using this to hold a small auto-feeder. Please don't print some of these and think that you can stack a bunch of stuff on them.
