The only complaint I had with the CR-10S Pro is the feed angle of the filament into the sensor block was so high that it would shave the filament going in and make a mess. This funnel solves that issue. Now there's no complaints! (well, PLA on PLA squeaks a little depending on the brand, but I just leave the room.)
If this piece helps you, tips are welcome and always appreciated! (But not necessary)
Update I noticed it wiggles a little, so I've changes the status to WIP. I'll play with it a little to perfect it.
