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.
NOTE: Use v5 files as they are most current version. Other files are kept only for legacy purposes.
Requires:
Everything press fits without glue. Enjoy!
Models exist for the following nut sizes:
UPDATE 21 May 2017: I tweaked the model and made version 5 with better wall dimensions and tighter nut openings. I also created a "fat" version that is flush with 1/2" nuts and flush with bearing cap.
UPDATE 08 Mar 2017: I added models for metric M10 or M12 nuts.
UPDATE 20 Feb 2017: I modified the scad file to scale based upon different sized nuts based upon measurements from https://www.fmwfasteners.com/blogs/faq/hex-nut-dimensions. I added models for 3/8" and 1/4" nuts.
UPDATE 15 Feb 2017: I modified the scad file to add chamfering to outer edge for a nicer feel in the hand.
UPDATE 10 Feb 2017: I modified the scad file to be able to specify normal knurling or inverted knurling. I also uploaded stl files with inverted knurling for 3 or 2 weights.
