A friend asked to replace his metal aquarium cooling solution with plastic to prevent corrosion.
Using the 120mm Fan Grill provided by reddaugherty, this takes 2 x 120mm fans, mount a grill to the top with existing screws, and then attach 8 legs to another grill on the bottom. Just use a screwdriver to screw through the leg and grill, into the fan. Then the fans can pull cool air from the ground to blow at the tank or remove hot air depending on the orientation of the fans.
Printed with PETG, .2mm, no supports.
The author remixed this model.
Expanded so that there are two fans in one grill, and added legs to raise it up off the floor.
Included is the file is one grill and one leg, but the idea was 8 legs and 2 grills total for the solution.
