About this 3D model

I loved seeing marble runs or any of those types of toys in store windows when I was a kid but I never owned one. I designed this (ongoing) set as a gift to my younger cousins this Christmas. I'll be updating the files and adding as I go. Enjoy! UPDATE: The new marbleRun-swirl works great and was a hit with my cousins! I just wish I could have printed more parts for them!
