My six years old daughter solved a problem regarding the toothbrush and toothpaste location at the bathroom. She designed (sketchers are included) and printed this thing. I draw it using FreeCAD. She loved to see how her sketch became a 3D model. We hope it will be useful for you all.

120 x 120 mm
M4 holes (separated 89 mm)... we took advantege of two holes that there were already at the bathroom wall.
