Algae/Urchin Cage
thingiverse
just a simple cage for either my dragons breath algae or the stupid urchin that keeps wanting to eat it up.... god I'm sick of that little prick.... Two files one is the main cage and one is the lid. lid and cage have 2 sets of 2 M3 threaded screw holes for hinges. Alternatively you can just use a couple zip ties
