This is a set of covers for a Fluval Roma 90 Aquarium. You can either use the 3 interlocking covers to replace the cumbersome and flimsy front cover panel, or include an auto-feeder mount which replaces the right-hand cover (fit left and right first, then centre slots in).
Any standard 70mm auto-feeder with a clamp mount can be accommodated. The internal food chute is designed to avoid food adhering to it and to minimise evaporative loss. It needs a minor wipe every month or so, to remove adhering flake, but nothing of significance.
I have been using for about a year. The permanent auto-feeder is a game changer because your only restriction on going away is how long you can leave the tank without a water change. I am using isolated planters and a fairly low fish stocking level in my set-up and so I can stretch a water change to 3-4 weeks if needed.
I am guessing that energy use is a little lower and temperature more consistent because of the insulation from the low in-fill density

If you want to mimick my set up completely. I have been using a Petbank CY009 battery (USB re-charge) feeder. It’s been reliable, but I have had to tape the food outlet because my chosen setting is between 2 ‘clicks’
I printed in PETG since it is both waterproof and UV resistant. 0.15 layer seems a reasonable balance between finesse and strength when coupled with 25% gyroid infill. To allow for the interlocking you need some bed contact support, but it removes easily enough (included within the gcode)
