Nano Frag Rack

I needed a multi-level frag rack for my coral QT. I am using a WaterBox 10g cube but of course this could work in any tank. The bottom piece is meant to be used as a weight, I used eMarco cement as the weight material. Note you really can't use infills on this as it will float otherwise. I designed in some pins and holes to help align the pieces. I used superglue to assemble the pieces.
