I wanted an Easy wall mount to put my steering wheels up out of the way when I was not using my Sim Rig. This is designed to use the standard hub to lock the wheel onto the mount just like onto the drive motor without damaging any connecting  pins. I did design is a little tight to make up for long term use. I did do a 5 layer wall and 25% infill for a very solid piece in my slicer. 2 screws into a 2x4 in your wall is recommended. It is made for #8 drywall screws to fit the counter sink.
