Filament Faucet (by Nigeke)

Filament Guide on Top of Prusa Frame (AKA the Filament Faucet)

If you, like me, have your filament rolls not on the T-bar on top of your Prusa Frame then this could help.

The Filament Guide (AKA the Filament Faucet) can be used with or without PTFE tubing (As filament guide on the other side of the PTFE tube the Filament Guide Wall or Shelf (by Nigeke) could be used)

What you need:

1. The Printed Part

2. PC4-M6 PTFE Hose Connector (Collet)

3. M6(sp1) Bolt

4. 5 mm flexible tube-brush

5. Sharp knife

6. PTFE-tubing; Outer diameter 4 mm; Inner diameter 2.5 mm

How to:

1. Print the part, in material of your liking, use 2 mm shell thickness and 20% fill;

2. Cut out the little supports in the top of the Clamp;

3. Use M6 Bolt to clean the printed thread with moderate force and keep straight;

4. Screw in the PC4-M6 PTFE Hose Connector (Collet);

5. Clean the hole with the flexible brush;

6. Click the Filament Faucet on your Prusa Frame and connect your PTFE tubing.

Notes:

1. Only .stl provided, no bgcode/gcode files:  Use Prusa slicer to make your own (they are printer/material dependent anyway)

2. Use Material of your choice, I used ABS as it smoother but also more brittle than PETG, so maybe PETG is best choice

3. Don't use a M6 thread cutter on the Printed Part to clean the thread, I did but it's and shredded the material. The bolt method works better, if needed you can also warm-up the bolt.

4. Make sure to use correct PTFE tubing: Outer diameter 4 mm Inner diameter 2.5 mm. Lot of sold tubing with the said inner diameter is NOT that, check it when you receive it if anything below 2.3 mm send it back, as you got old standard dumped on you. A smaller Inner Diameter can cause difficulties with leading the filament through and that is incredibly annoying! 

As PRUSA said: HAPPY PRINTING!
