I like the way the Filament Guide made by OzShooter connects to the frame of my Ender 3, it has been much sturdier than other options I've tried.

I was just looking for a simple way to store my scraper and cutters while keeping them easy to get to. I had printed a different frame hook previously but it sagged and allowed for the scraper to slide off the end.

I did a pretty simple remix of the filament guide and am very happy with how this turned out.

V3 lengthened the hook, added a bit of an angle so my scraper doesn't fall off the end and added a bump in the middle to keep my scraper and cutters separated.
