Direct Driver extruder Bowden hose upgrade

After replacing my Jhead with a chimera dual extruder i had the need for an attachment upgrade for the bowden tube. My Prusa i3 has a direct drive with metal parts so i really like those and don't want to replace them with printed parts.

So i designed an attachment which fits on the two screws of the direct drive and creates an attachment hole for the bowden tube. The bowden tube makes use of the pre-drilled holes of the metal parts and can be set to stay right before the extruder gear. This
