Typewriter Ribbon Spool Winder

I didn't want to manually wind the new ribbon on my typewriter with my hands again (it took forever) so, having had 2 hours free time, I created this little tool.

Printing:
I've printed mine in PETG with 0.15 layer size, standard 15% fill.
You will need to print 2 copies of the little knurly knob.

Needed extra parts:
2xM5 30mm screws

Assembly:
1) mount the handle on the lever with the printed large screw so that it can still turn freely but without wiggling
2) thread the screw in the base
3) thread the screw in the lever
4) screw the lever outer part on so that the whole can turn without wiggling
5) mount the spools, the one sitting on the driver screw should be tightened with the knob so that is turn with the handle; the other one needs the knurly know just to avoid running out of the screw.
