Customizable Spool Holder

UPDATE 6/29/2018 -

I've added a small lip inside the bearing cutout. The outer ring of the bearing will rest on this small lip so that the inner ring will not touch the plastic. The spool holder spins much more freely now.

I've added an option for a "hollow body". Set the new variable, BodyType, to 2 for a hollow body. Set it to 1 for the regular body. The hollow body has extra cutouts in the center body. Why? I thought it was an interesting look and reduces weight a little more. Why? Eh. Why not.

I've changed the defaults a little. The default body type is the regular full center body (BodyType=1).

I've updated all the STLs so that it includes this lip. I've also created STLs for the new body type.

UPDATE 6/28/2018 -

I've updated the OpenSCAD file to add some more customizations. The number of arms, the thickness of the arms, and the type of arms (full or thin) can be specified.

Thin arms will be more flexible and
