Corner Connector

I printed these to make an enclosure for my 3D printer. This is just a basic corner connector i created to connect clear plastic sheets for my enclosure. They are strong and are working flawlessly right now. These are temporary until i can get metal ones from the hardware store due to the fact warping might occur from the heat that gets trapped inside the enclosure. So far there has not been any warping and have printed ABS and PLA many, many times while using these as the corner pieces.
