Designed to be partially buried in sand, or place a rock on the lower ledge to hold it down. The natural tendency for 3D printed parts is to float, so semi-submerged or weighted down works best.
Holds frag plugs up to 1/2" stem in your choice of 36 holes, so no matter how big the plug your sure to have space for it. Or leave a clear space around those stingy corals.
Size:
7.5" Long
2.5" Wide

Due to its size, it requires a medium flat rate box to ship. Maybe throw in a few other items to make the shipping worthwhile. Maybe a few mushroom box's or bristleworm trap.
