Summary
I love the tri-spinners and I have made them for many people. I just don’t like having to use 4 608 bearings for each spinner with 3 of them just used as counterweights. I found that 1/2 inch nuts have about the same weight/size as a 608 bearing, so I modified the spinner to use them for counterweights.
I also modified the the knurling in the scad file to have not have partial knurling on the edges. I am a bit of a perfectionist.
This project is a remix of my other spinner but the nuts and bearing caps are flush.
Requires:
1x 608 bearing
3x 1/2″ nut
Everything press fits without glue. Enjoy!
