Rotating ornament_Space jumping

It's a interesting table decoration, when it's rotating it looks that the space is jumping, a vision beauty for decompression. you can put it on you home or office, when you feel tired you can play with it. You need a bearing of MR105-2ZR, or you can use other bearing on hand but need to modify the design to match the bearing. Below pin show the bearing assembly Support is needed or you can separate the model so that could remove support. 0.12mm layer thickness is recommended for higher quality. I cut the assembly shaft in half so that when printing, the material is stacked in the axial direction, so it has higher strength in the radial direction and is not easy to break. Two models are uploaded, one is the assembly model that you can modify, another is the model for printing that shows the parts layout. See below pic
