About this 3D model

Because my towel hangers kept falling of the wall I had glued them to, I came up with this alternative solution: attach the hanger to the tap. Design split into two parts so it can be printed without supports for a clean look and minimal postprocessing. Circular part has an inner diameter of 36 mm and snap-fits onto the tap (just bend it slightly and push). The second part can simple be attached to the circular part using a pair of M3 screws of 20-30mm length. I recommend to adjust the length and diameter of the different parts to your needs. To do this you can use the solidworks or step files.
