About this model

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 UPDATE: This has been superseded by Thing 3055127 which provides designs for all nine right-angle connectors. Also, this version has a bevelled outside corner for improved printability.
