Parametric aquarium shrimp tube

thingiverse

In order to give my new amano shrimp in my fish tank I was considering to order shrimp tubes. But then I doubted about the size I needed, and looking on Thingiverse I found at least two promising designs. But when slicing [3DHorton's design](https://www.thingiverse.com/thing:3278573) I found that the walls were not matching the standard line width of my printer so that Cura tried to complete with time-consuming infill here. So a quick visit to OpenSCAD and here is my parametric design. You can easily controll the width of the walls, the size and length of the tubes and finally the number and arrangement of tubes. Now let's wait what my shrimp will think of their supposedly new homes when I introduce it into the tank tomorrow.
