The bear has been modeled in Blender, the other parts and the assembly was done with Fusion 360. Two magnets are used to fix the holder.
The bear has been printed with wood filament and painted with wood oil. The other parts were printed with a Bio Filament in color "Nature". The bear can be rotated so that only a little support on the magnet part on the back is needed. The top holder does not need supports, and the shelf on the bottom needs a little support on the magnet installation part an the little rectangle for easy assembly.
