With this PTFE adapter, you do not need to drill holes into your Sunlu FilaDryer S2 to attach it. The connector is attached with some double-sided tape. I used 3M VHB foam tape, it is strong but easy removable.
You need to remove the small tube part in one of the holes of the FilaDryer to have a better angle of the PTFE tube into the dryer, just push it out.
You need the following parts.
