About this 3D model

A butterfly push toy I designed for my grandkids, nieces and nephews, but my wife and kids liked it as well, so I guess I'll be printing more. Video is here: https://www.youtube.com/watch?v=2gHOx2oNcpc. All pieces are printed with the exception of the wide rubber bands used for traction. Designed using Sketchup Make 2015, and printed in PLA on a Makerbot Replicator 2 using Makerware 2.3.3.42 "Standard" Settings (.2mm layer height, 2 shells, 10% infill).
