Spinning on a peg
In order for the spinner to spin, it will need a peg to spin on. The problem is that a
traditional joint wheel and peg doesn't allow the object to lay flat for 3D printing
no matter how it is turned. So making something like this work requires a little bit
of creativity. Instead of a peg through the spinner a peg can exit out one side of the
spinner and a hole can be made in the other side for another peg to mate into it.
The trick is that any time two objects are connected after printing, the goal
is to think about friction. Since this spinner needs to spin the goal will
be to build something that will hold the spinner in place enough that it
will not shift position too much but loose enough to minimize friction so
it can spin freely. Later on the box will be designed with extremely tight
tolerances to increase friction since no movement is necessary.

Add
(

) a
UV Sphere
and adjust it so it has a radius of
2
and is moved
(

-4
down the z axis (

) so it is sitting somewhat below the main spinner.
Name this sphere
