Here is a mount for the adventurer 4 with the new filament runout sensor. You can find detailed information and pictures of it in use here:https://www.printables.com/model/318946-adventurer-43-custom-extruder-mount-new-style-runo The filament senor can be glued into place or using the screw holes depending on what type of extruder you use. There is a file with no inlet hole (directly inserted into the gears for less tension) and one that has the hole lined up with my official Creality extruder. I have also included the F3d file to edit and move around the hole to whatever extruder you want to use. PICTURES IN THE PRINTABLES LINK.
