I'm currently working on such an extruder Also has holes to add inductive sensor, BLTouch etc. like in the picture - you can connect via four 3x16mm Woodscrews. The sample inductive sensor holder STL is for C-Lin PL-08N (works plug&play), bought from Zonestar on Aliexpress -->You need a drill to make tight-enogh holes for the fixing M3 screw(s).<--- (2mm or 2.8mm drill)
