Fidgeting can help with concentration, relieve anxiety, or just give you something to do. I am constantly playing with random objects with my hands when I am thinking and creating. Some are not so quiet and possibly disruptive to others(see video). When I discovered these simple fidget tools - yes these are tools -
I knew I had to make some.

- However they are not needed for these larger bearings if you don't want them - personal preference.
This is my favourite(different model shown):
*** Due to the nature of 3D printed parts in general, occasionally some parts may have quite a tight bearing fitment. I have only experienced this on very few instances, but it should be mentioned that occaionally a small amount of material may need to be removed to help insert the bearing. A vice works well to install when your fingers are not able to do so. Majority of cases will be able to be installed using just your hands.***
