Shout out to Ernesto Pineda for his original design which is a simple fix to the CoreXZ filament tangle issue, without throwing extra weight on the gantry. Original design can be found on Printables at https://www.printables.com/model/1069939-ender-3-v3-filament-sensor-mount. This mod extends the front surface and adds snaps so the mounting fits more securely. See the original design for more pictures till I get some up.
The design utilizes existing mounting bracket, screws, and bowden tube. Though tube can be replaced with longer version if you think needed. I didn't.
With machine off, and filament removed, unmount sensor. You will need a 2mm and 2.5 mm allen wrench. Two screws attach sensor to bracket. Two more attach bracket to Y axis. Keep original parts for the mod.
To assemble, screw the original bracket to the printed bracket using original screws. I recommend doing this off the printer for ease of taping screws into printed part. Then attach sensor to original mounting bracket. Reattach bowden tube. Snap assembly to siderail mid height so that the bowden tube and hotend wires reach the homing area and the full down area. Snap in setting the rear surface first, then snaping the front.
Ta-Da. no more slack filament.
Sorry, I really don't know what the clip on the modified mount is for, I didn't use it.
