Anet A6 improved top spool holder for spool rocket

I decided to redesign entirely this spool holder myself with new cotations and to make it wider to accept the spool sprocket design from jadames : https://www.thingiverse.com/thing:2067525

It's not to wide so you can reuse the original threaded rod and the 4 nuts like shown in the photos above.

I prefer myself this design because it's not going to bend the acrylic frame caused by a not centered gravity point (like with this design : https://www.thingiverse.com/thing:2009565).
