I've seen this folding dressing doll at an exhibition of the Kindermuseum about communication. My girls played nearly half an hour with it, so I decided I could create one myself. Unfortunately none of the supervisors could tell me if the design was an original by the creators of the exhibition or if they had seen this somewhere else.
The build was done on a desktop cnc-machine by Stepcraft from 6.5 mm beech plywood using a spiral-toothed 1.2 mm flute. The doll itself is made from 2 mm birch plywood.
