Has anyone ever tried to 3D print an icelock?
Looks simple enough, but I wonder how sturdy they are.

Me. They work great! However you have to anneal the plastic beforehand to make it more water proof and stronger. Also sand the thing to allow the piece to slide out with less resistance such as letting it fall out. Also with this one I would recommend drilling a hole through to allow air to get in.
