Bowden extruder funnel for 1.75mm filaments

I grew tired of having to unscrew my BSP push-fitting in order to correctly feed the filament through my [MK8 bowden extruder][1], so I made this little funnel to allow it to be fed more easily, sliding automagically into the BSP fitting and then into the bowden tube. It's made for 1.75mm filaments.
