Bowden Extruder for Robot Digg

I have a Robot Digg extruder:
http://robotdigg.com/product/70/MK7-Molded-Drive-Block

for a little while, but I have not been able to use it, in a Bowden configuration, so I finally got around to designing this.

The OpenScad file is included, but quite messy,

I did have a fillement runout during printing,

But still good.

I would recomend printing at a high infill, I printed this @ 40%,
which was not quite high enough for M5 tapping.
So I had to oozzee some Super glue in !!
