@jstsmthrgk Sadly, I have really little experience with openscad and at this point too little time to get used to it. I guess there is no simple converter available?
@Potassium I made some after the last congress for my daughter. You may want to adjust its size... Use it any way you like, probably also as a bad example of how not to do things in #FreeCAD. https://bloechligair.ch/catears.FCStd CU@39c3!
