Spool holder for Anet frame

I found this spool holder (https://www.thingiverse.com/thing:1829846) but the diameter was higher than some of the spools I have so I decided to reduce the diameter and also added a stopper at both ends so the spool doesn't fall from this roller.

The diameter of the spool is 43mm and the inner circle that will hold the threaded rod is 8.5mm so it fits ok.

I tried to design it as close as the original but I had to start from scratch

I also had in mind, as the original designer, to avoid supports when printing. It doesn't need any support.

Please comment if you found this spool useful.
