Aquarium Overflow Box [Fixed and improved Version 2020]

This is my enhanced version of the Aquarium Overflow Box by MrLunk.

Changed:

• better flow rate
• added a connector to attach a 22mm hose to the outlet. No need to glue or stick in a hose into the hole in the model which would never be really watertight
• corrected errors in the original that can cause failed prints or water leakage
• added a fish weir on the intake so you dont have to fear that your little friends escape through the hose :)

General Notes:

This overflow box works on a physics principle. To make it work, you need to put it underwater and rotate it underwater a little, so ALL air is coming out. It needs to be filled totally before you can slide it onto your fish tank. But then its working perfect. It will always transport the amount of water that is reaching the surface of its intake out of the aquarium.

This is perfect in case you have a pump that is pumping up water into your aquarium and you do not want the additional water to fill up the aquarium and run over its edges.

If you have some little aquarium under your fish tank where you put in all your technical filtering stuff, you can create a wonderful cycle of filtered water being pumped up into your fish tank and exceeding water running down into your filter aquarium.
