A simple shelf that fits on the inside of (most) cabinet doors and which can hang two kitchenaid attachments. Originally it was designed to be secured to the wall or cabinet with several countersunk screws but it also works well using command strips or other less permanent methods.
When printing, I'd recommend paying attention to the layer orientation in the hangers themselves. The weight of some attachments can be a little much if your layer adhesion isn't stellar and the orientation isn't right. My first one failed, and I ended up printing it in the orientation shown in the .stl so that the perimeters of the hangers were in tension. It's a little less pleasing to the eye that way, but it held the attachments better.
The author marked this model as their own original creation.
