Frag Rocks

3D printed Frag Rock for the reef aquarium. I was recently searching for 3D printed frag rocks, and sadly I wasn&#39;t very fond of the ones I found. I wanted some more exciting curvatures. So I decided to make my own. These are meant to go in the sand or on a rock. If they are on a hard flat surface the frag plugs won&#39;t seat fully into the &#34;rocks&#34;. They are hollow underneath so they do not displace much water volume. There are three versions currently: Standard V2 - I have increased the size of the frag plug so that it should be able to fit any frag plugs at all. The standard should fit most frag plugs, but there are some with a wider base (~12mm that wouldn&#39;t fit. I also increased the size of the plate to 25.5 to ensure it&#39;ll fit everything.). Standard - Should fit most standard frag plugs. They fit most of the ones I have been able to test. ( < 9.25mm Stem & < 25mm Plate) Nano - The Nano uses a smaller frag plug. I based it off a measurement I found on Marine Dep
