This is a mount for an automatic feeder which can be found here: https://www.thingiverse.com/thing:2959685. You will want to print all the parts from that link except the tank mount and end cap.
It will fit the Fluval Flex 57 (and probably 34).
It's a tight fit, so there's no need for adhesives or anything; just push in the body and rotate to make sure the holes line up.
Supports:
Yes
Notes:
Bed only supports are all you need.
