Aquarium Overflow v2a (a better version)

A simple Aquarium overflow for small aquariums.
Printable in 1 piece :)

When printed insert a 9/12mm tube in the hole and glue it tight.

The example in the image and video are flat at the top, to save some material and printing time I made it into a triangle :)

Usable for stacking several aquariums with a sump / filterbox at the bottom.

The other one you see in this video is the 1st version I made, files here:
