Filament Roller Guide Bracket

I like the Ender 3 Filament Roller Guide a lot, but found that the filament
rubs slightly on the bracket as it comes off the roller.

I shortened the bracket a few millimeters, which eliminates the rubbing.

I've posted the FCStd design file as well as the stl file for my modified
version.

I based my FCStd file on the one from @mkrmec.

Thanks to both @Holspeed and @mkrmec.
