I tried to use the Base Spool Holder from this Model to use it with this Remix.
But it does not fit.
You know why?
The origin Spool Holder has a left-hand thread, but the remix needs a right-hand thread!
Costs me hours to detect the problem.
So I created a new version of the Base Spool Holder, but with a right-hand thread!
And here it is.
