2-piece Universal Spool Holders for FFC Pro

It's a remix of another design. This one prints 2 spool holders in less time than the other design prints 1 and it's a bit lighter on materials.

If you apply a decent amount of acetone to the inner bevels of the parts that connect to the printer and the outer bevels of the "rods" that hold the spools, the 2 parts will fuse into a single piece which can easily handle 2.2Kg spools from any mfgr

I've been using these for a week now and they work great.
