This is a quick cage clip I created to hold down the lid of a tank that we received to house our new corn snake as they like to try to escape. Very easy to clip on and holds the lid down firmly.I made a few measurements with my calipers and modeled this clip in Blender. I exported the STL from there and opened it up in MakerWare for a test print. I printed these in black PLA on my Makerbot replicator 2 and they appear to be holding up nicely!
