Breakable Coral Grow-Out Frag Plugs

Wanted to create a Frag Plate design that was “breakable” for encrusting corals and Zoanthids. As always, anything you're printing for a Reef Aquarium needs to be printed in PETG - Do not use PLA! Since PETG is somewhat flexible, an razor knife is recommended to separate the plates after the coral has spread. I'll post an update in a month or so if this idea works.
