Ender 3 S1/S1Pro Filament Sensor Holder with PTFE Tube Guide for Sunlu S2 Filament Dryer or others too.

Purpose: Create a humidity-proof and smooth guide tube for the filament sensor, designed for personal use with the intention to share with the community.

MATERIAL LIST:
3D printed parts;
2x M3x18mm Original filament sensor screws;
1x T-Nut Screw (spare one from the printer;)
3x M3x8mm Screws;
4x M3x4mm Heat Staking Threaded Inserts;
2x M4x8mm Heat Staking Threaded Inserts;
PTFE Tube Kit for 3D Printer with M5 Push-in fitting threaded straight.

Assembly:
Part: Filament Sensor Holder.stl

1. Carefully insert 4x M3x4mm Heat Staking Threaded Inserts into the designated holes on the surface labeled "Sensor." Note: Keep insert temperature below 220°C. Clean around the melted plastic.
2. Gently insert 2x M4x8mm Heat Staking Threaded Inserts into the wall holes. Clean around the melted plastic.
3. Attach the sensor using 2x M3x18mm screws to the holder, ensuring alignment of the filament sensor hole with the M4x8mm insert holes. If alignment is off, carefully adjust by reheating the M4 inserts and realigning.
4. Cut a suitable length of PTFE tube (e.g., 38cm) from the dryer to the filament sensor. Shave and screw one end into the M4 insert at the sensor end.
5. Repeat the process with a shorter piece (around 2cm) of PTFE tube for the other end.
6. Gently guide a 50cm length of filament through the PTFE tube and the sensor. If it doesn't move smoothly, repeat step 4 double check where it stuck.

Part: Adapter.stl

1. Attach the 3D printed part to the rear of Part 1 and secure it with 2x M3x8mm bolts. Ensure a tight fit.
2. Place the T-Nut screw at your desired attachment point on the printer and tighten it securely. You can also secure it from the bottom if needed.
