About this 3D model

It is a very simple parts for the flying extruder mod on Flsun QQ-S. You will need an M4 nut and an M4 8mm or 10mm. You can also put a ptfe coupler but it is unnecessary. It is designed with very tight clearance, so the ptfe will be blocked and no coupler will be needed, just be care about dimensional tolerances of your printers. happy printing.
