Space requirements meant I needed a backshell for a D-sub connector that had side entry cabling and a small footprint. It come in two parts that are glued together. The cost of 2 screws is 4x more than the plastic, so it's pointless having them. Cable clamping is provided by slots for two cable ties inside the shell.

Assembly: Wire up the plug, put it in the bottom shell and clamp with cable ties. Apply glue to the tops of the pillars and attach the top half.
