This thing is a bracket that holds up a piece of 14 mm eggcrate using suction cups from a spare MaxiJet powerhead. The eggcrate platform can then be used to hold coral frags inside an aquarium until they have grown out or until you are ready to sell them at a local frag swap.I have provided a plate with both one and two of these brackets.NOTE: I included the SCAD file in case you need to adjust the size of the suction cup hole.I recommend any of the three coral frag plugs here on Thingiverse:Print the brackets in either ABS or PLA. Print the frag plugs in PLA since they are more dense.
