Snap-on filament guide

Like the guide but sometimes my filament would come out. Changed it so that the gap is 1.75mm and is at an angle that will make it unlikely to accidentally come out even after wearing down the opening. Also make a version that is slightly longer since I'm using it on the Tronxy XY2-Pro instead of the X5S. I'm also using Tronxy XY-2 Pro filament guide (625zz bearing) by Negativist May 22, 2020 over the filament run-out sensor and they both work great together.
