Spool Axis Support with zz608

I'don't know who the original author of the stl is. The stl, was on my hard drive a long time ago.
Simply, I have increased the scale and I have merged it.

You need two ZZ608 bearings, to make it work better.

Practical for SUNLU filament rolls, and similar ones, which have a larger central diameter.

If you think you recognize the original author, please let me know to give you your credit.
