Modular Floating Fish Fry Isolator

** Modular 3D Printed Fish Breeding Box System **

This is a modular 3D printed box system designed for aquarium use, suitable for fish breeding, fry isolation, feeding boxes, or creating custom compartments within a tank.
The system uses two panel sizes: 60 x 60mm and 60 x 30mm. Each panel size is available in two variants—with 4mm or 2mm round holes—offering options for different levels of containment. The 4mm holes are generally suited for fish fry to pass through, while the 2mm holes are for isolating fry or fish.
Panels connect using four different connector types, allowing for a wide range of configurations. You can build single or multi-chamber setups in various orientations, and expand or reconfigure the system as needed.
For aquarium use, these parts should be printed in PETG only. PETG offers better water resistance and durability in submerged environments compared to PLA or other common printing materials.
This system is intended for freshwater or saltwater aquariums and is suitable for anyone needing a flexible and reusable enclosure system for breeding or fry management.
