I am 3D printing hanging coral frag racks that I designed. It has several advantages over the traditional magnet racks that attach to your glass.
- Keeps your display clean without blocking the view into your tank
- No magnets that can rust and poison your tank
- Can be placed anywhere in your tank, not just along the perimeter
- Add or remove frags without getting your hand wet! Just pull the line up with the attached rack.
- Frags get great flow and light
- Can be used on large tanks with thick glass (no magnets)
