About this 3D model
Do not hate me for making it :) It is a present for a friend's teenage daughter :) I used "Inkscape to OpenSCAD converter v5" (http://www.thingiverse.com/thing:25036) to make it. This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/iGH14Uq6oqg https://www.youtube.com/watch?v=uGj_GrdLkck
