This is a model to mount your Bigtreetech SFS v2.0 to the stock extruder of the FLSUN Q5. It requires the printer to be opened up and the extruder to be completely unscrewed as this gets placed between the extruder and the motor. you may also want a small piece of PTFE tube to feed from the SFS to the extruder opening. The tube must be 5-6cm long.
You may need to reorient the model in your slicer to be printed on the flat side
Edit: There is a 2nd version that is stronger
