Shrimp Cave

This shrimp cave is designed to help freshwater shrimp, such as cherry and crystal shrimp, stay safe and reproduce. The cave is placed in the substrate and stays in place by pushing the substrate against the sides. I printed mine in PLA and have had good results with it. The cave fits snugly against the glass which allows for fun viewing opportunities. I am still very new at designing models so I'd love any feedback you can provide, and it would be great to see any prints anyone does.
