Parametric aquarium shrimp tube

thingiverse

I was thinking of giving my new amano shrimp a home in my fish tank by ordering shrimp tubes, but then I wondered if I had chosen the right size for them. While browsing Thingiverse, I stumbled upon at least two promising designs that caught my attention. However, when slicing [3DHorton's design](https://www.thingiverse.com/thing:3278573) with my printer, I encountered a problem. The walls of the tubes didn't match my printer's standard line width, so Cura tried to compensate by adding infill, which wasted valuable printing time. To solve this issue, I quickly opened OpenSCAD and created a parametric design that allows me to easily adjust the wall width, tube size, length, and arrangement. Now, all I have to do is wait for my shrimp to move into their new homes tomorrow and see how they like them!
