So far best MK10/MK8 extruder bracket. It can handle 40D flex with 60mm/s or more speeds. It has spring tension regulation also.
I do recommend printing with slight over extrusion, it does help with parts strength.
Might need some teflon tape to hold in place PTFE coupler, depends on extruder calibration etc (with over extrusion you don't need that)
I do NOT recommend printing "without_drilling" version, filament path isn't that smooth then. Read post-printing
Use standard included lever or whatever you call it in English. If your one is broken I'm pretty sure that this one would work just as well https://www.thingiverse.com/thing:2492903
I use 1.0V Vref, I don't think that it will be jamming with lower Vref, but if it does, just increase your Vref by using motherboard potentiometer
