I have a brain coral that really loves his spot on the back wall of my tank but he was really over growing the frag shelf he was on. I searched and search for a solution and finally got it all set for my buddy Brain.
I found a shower shelf 3D print file and enlarged it a bit, then I glued 2 frag mounts to the bottom. It took 2 hours to print and it’s printed in PETG on my Elegoo Centauri Carbon.
At first I glued just one mount at the back center and that was no good. Tipped my coral right off. I removed that mount with bone cutters and re-glued it plus added one and now it’s sturdy.
I wish there were more frag mounts for mounting corals on the back wall of your tank. Especially corals that like to spread out.
