Simple Aquarium Swim Through Cave

This simple swim-through cave is designed to sit against the front or side glass of your aquarium. I already made a popular corner cave, so I thought I’d add a version that works along a flat surface.

Great for fish, shrimp, and snails – gives them shelter, play areas, and a safe retreat.

Dimensions: 150 mm (L) x 50 mm (H) x 50 mm (D). You can scale up or down to suit your tank size.

I printed mine in PLA Matte, but you can use any filament that’s safe for aquariums.
