The original requires a new self-tapping screw. This one reuses Qidi's own from the side spool holder.

Threaded PTFE Connector Holder

GD.Design's original PTFE tube guide has a tiny pilot hole meant to be used with your own self-tapping screws.

But Qidi's PTFE tube connector for the spool holder already has this screw:

Why not use it? So, I made a remix with an exact thread to match the screw :)

Printing Tips

The screw's thread depth is only ~0.325 mm radially, so print accuracy matters. The best way is to print it upright with 0.12 mm layer height.

But that increases the print time a lot, so I used variable layer height to only use 0.12 mm for the thread section and 0.20 mm for the rest. I attached my project file so you can just use that.

Let me know if you have any questions or concerns, I'd be happy to help.
