A 3d printed shelf to put items such as a smart meter (or other objects). The part uses the 3 pin plug to hold the shelf in place. The part should be printed with the plug side on the bed with no support material. Testing with a plug proved the power from the socket still goes through.
I uses low quality 0.3mm layer height on my printer and it came out fine, Some of my dimensions around the plug pin were a little tight but I used a knife to open it out a little. I've loosened the tolerances a little to fit a bit nicer in the file uploaded.
