Elegoo Neptune 4 (Pro, Plus, Max) 45 degree bracket for filament runout sensor.

Update information: I saw a post on reddit where someone wore through the brass bushing on their runout sensor. After checking mine (with about 120 hours print time after using this bracket, only PLA without any abrasive type filament) I am noticing a small groove forming in the brass bushing on the underside.  I assume always having the filament rub on the underside at this 45° angle would wear it out faster then when it's mounted paralel to the path of the filament. I made a 45° bracket to mount the filament runout sensor ontop of the Neptune 4 Pro, Plus or Max (mounts to the T slot in the metal rail).My enclosure it fairly tight on top of the printer, I have the filament come in from the back, and the 90° bend seemed a little steep.The filament sensor itself mounts snugly inside with the metal peg on the under side, if you want to retain the loose side to side movement you'll have to file or drill out the hole a little. I'm using (as pictured) what I named runout sensor v2, I stacked washers with the original mounting screw. (you could use a shorter m4 screw instead if you have one)Additionally I made 2 models that are fully thicker, or have a built in spacer, so you don't have to stack spacers with the original screw like I did.
