Super Rack - 67 Frag Capacity

I noticed a lack of large frag racks on here for us serious fraggers, so I decided to create one. The rack is held by two magnets, about 26mm in diameter. Spray some kind of clear coat or paint epoxy onto the magnets being glued to the rack to prevent any metals from leaching from them. For the magnets outside of the tank, glue some kind of fabric to the side contacting the tank to prevent scratching.
