About this model

Designed as a science fair project for the grandkids, this model can be used as just a 3D printed runaway escapement spring motor demonstrator, or with the additional drive components, a 3D printed runaway escapement spring motor car. The grandkids have a 3D printer and as such will 3D print their own parts, although I may have to assist just a little with assembly, but hey, it's fun to have some grandkid time! As usual I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes. Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.12.1, and 3D printed in PLA on Ultimaker S5s.
