Some shameless self promotion here, I like my own extruder best ;o)

My original extruder was made from laser cut acrylic parts that looked really nice but wasn't strong enough for my hands. It broke after a few prints so I had a try with this one from Thingiverse .
It worked really well but I liked the closing mechanism of the original extruder better and also I still wanted to hang the extruder from the top of the printer together with the filament holder.
So I had a go at it myself and it works really well for me Kis Bowden Extruder
Here is a picture on the printer:

I never used a Wade extruder so I can't tell about those, what advantages do the gears have?
