About this 3D model

https://www.reddit.com/r/3Dprinting/comments/jdg4u1/i_made_a_tiny_fidget_spinner_for_my_tiny_3d/ I made a tiny 3D printer, and knew I needed to make some tiny things to go with it. I had some really small bearings from another project, so... things you need: 3d printer four 3x6x2.5 bearings (https://www.amazon.com/s?k=3x6x2.5+bearing&ref=nb_sb_noss_2) you might need to adjust tolerances based on your printer. use horizontal expansion. the spinner takes less than 10 minutes to print.
