Square Tubing Corner Connector
thingiverse
This is a three-way corner connector for square tubing. The .STL file contains the nominal dimensions for 1/2 inch square tubing, but you may need to make the inside dimension a little smaller (in the Customizer or in OpenSCAD) to give an easy slip fit. I used a very similar design to build an enclosure for my printer. UPDATE: This has been superseded by [Thing 3055127](https://www.thingiverse.com/thing:3055127) which provides designs for all nine right-angle connectors. Also, [this version](https://www.thingiverse.com/thing:3510041) has a bevelled outside corner for improved printability.
