Aquarium Under Gravel Filter

I designed this to be easier to print than existing under gravel filters. It is 140 x 140 x 10 mm and can be scaled in cura to fit other size tanks.

Base pieces can be cable ties together.

Uplift tube is hole is 20mm diameter, you may need to adjust Horizontal Hole Expansion for correct size. I just measured hole after printing and adjust size of my uplift tube diameter to match.
