Fluval Flex Aquarium Cooler / Cooling Fan 80mm

cults3d

After I bought a Fluval Flex 35l/9g (okay... just because it looked nice) I quickly noticed some flaws and / or opportunities to tinker :-) So I started to redesign and add some things. This is Part 1.1 of the project. The whole project will cover cooling, heating, light control, water refill (and whatever idea I will have in addition) using an ESP micro controller and without any destructive modifications at the tank hardware. I wasn't happy with this opening in the lid without any way to close it (apparently for feeding). And in addition the LED in the lid becomes quite warm and heats up the water, especially during the warm seasons. So I designed a cooling fan adapter for this which stays in place without any screws/clips/glue. This is the 80mm Version of https://www.thingiverse.com/thing:3640543 because sometimes bigger is better. To keep it printable without support structures I decided to design two parts. To attach the fan adapter to the schroud, 2x M3x12-16 screws are needed For fixing the fan to the adapter you'll need 4x M3x10mm screws. The holes in the adapter are 2.8mm and the screws will self-cutting their threads when inserted first time. please keep in mind: the cooling effect is better with the fan mounted to suck the air from the surface and blow it outside - but more water will evaporate in a shorter period of time published project parts so far: + Fluval Flex Cooling Fan Adapter 40mm https://www.thingiverse.com/thing:3640543 + Fluval Flex Cooling Fan Adapter 80mm https://www.thingiverse.com/thing:3671625 + Fluval Flex Filter Mod https://www.thingiverse.com/thing:3639353 + Suction cup temperature sensor mount for DS18x20 https://www.thingiverse.com/thing:3640844 + water level controller hose clip for Fluval Flex filter compartment https://www.thingiverse.com/thing:3675744 + Fluval Flex Intake Pre-Filter / Baby-Safe https://www.thingiverse.com/thing:3730658
