It was a tire I 3D printed using Formlabs Form 2. I then needed to print the flexible part of the tire from MakerBot 5th gen replicator using NinjeFlex because it elongates more, making the flexible part to be easier to assemble. After everything was seemingly perfect, it taught me how fragile resin is, along with the broken phone cases.

I 3D designed it using @SolidWorks. I 3d printed it using @makerbot and @Formlabs .
