That part works great, it just didn't connect the base of the thumb to the frame, the part that holds the rotating portion. The pic shows what I mean, the slicer created a gap around the rotating thumb frame. I'm thinking it is my slicer, using Simplify3D. I haven't really tried any other slicers so I'll experiment with some others. Little bit of super glue fixed the issue and my kid loves it. Thanks again for the fun print!
