Tri Spinner with Nut Insert

thingiverse

I quickly printed a custom nut insert using my 3D printer after realizing I only had one 608ZZ bearing available. To add some extra weight to the spinner, I decided to use three nuts as a makeshift solution so that my Granddaughter could take it to show and tell the next day without any further delays. To ensure a proper fit, I scaled up the nut holder in the 3D printer software by 0.7mm on both the x and y axes, as the initial design seemed too small - possibly due to shrinkage during printing. I then proceeded to test print one unit to verify its compatibility with the spinner frame.
