Hatchbox spool holder 4mm rod With a hole for a 608zz bearing,

The original Spool holder by fishbacon works great but had one issue the hole where the 4mm rod went gripped the rod causing the whole rod to move off the spool holder stand after awhile printing (if not checked on it would cause the spool to fall off the stand).

So I have recreated the model with a hole for a 608ZZ bearing its easy to press a 608ZZ bearing in then once it's most of the way in press the piece against a table to press it all the way in.

In your slicer rotate the spool hold
