I needed a small bowden filament guide mount for my drop box and the ones I found didn't attach well to my printer.

The 4 clamps are designed to fit 4mm O.D. bowden tubing. I found it easier to slide the bowden tubing through the clamps then to push the bowden tubing in to the clamps.

This design re-uses the M5x6 Bolts and T-Nuts that attached the spool holder to the Ender 3 Pro.

• 20% infill
• No Supports
• .2 layer height

I recommend printing this with the back of the holder on the bed of the printer. I did not require and supports.
