PTFE Tube Holder for Hesine M-505

I made this holder for a 4 mm PTFE Tube.
It mounts directly over the extrudermotor, as you can see on the picture.
The tube is held in place by a M3 screw, but the hole should by small enough to hold the tube in place by itself.
If using a screw be careful, not to tighten it to much, or otherwise the filament will get stuck in the tube.
