This part is designed to clip onto the side of a wire dog playpen so it can be attached to a surface. I removed the clips joining the foldable metal pen sections, so it could block access to a wide entry way. The pen's wire has an approximate diameter of 3.7mm.
I snapped the printed parts onto the wire, then attached them to the wall with high strength velcro. The gap in the middle is for a small zip-tie, in case it needed a more robust connection to the wire.
If the length of the wire gate is too long, it's becomes pretty easy to knock over.
