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.
You can print out this pdf at 100% or "Actual Size" to see if it fits in your hand and you like the size: http://www.idlehandsdev.com/fidgets/nnela/NnelaSize.pdf
This is The Nnela.
It takes skateboard bearings which can be found at any skate shop. You can also get bearings in the link listed below.
Other shapes and styles available in my store.
Bearing caps available here: http://shpws.me/MKOI - However they are not needed for these larger bearings if you don't want them - personal preference.
This is my favourite(different model shown):
***In the rare instance of a loose bearing fitment, a small dab of CA glue on the outside of the bearing will secure them permanently. Another method(my preference) a small strip of scotch tape, or similar thin tape, around part of the bearing causing a slightly more snug fit and more friction, while still allowing the bearings to be removed and replaced with other colours/types. I have only needed to do this on one early version of a model, and it was only after I had removed and installed the bearings several time. New version have much tighter fitment.***
