Da Vinci Pro Radius PTFE fix idea

DISCLAIMER - I don't have the "Pro", but a 1.0a, so I'm not even sure this 'fix' is enough for the Pro's jamming issue with the bend in the PTFE tube. (My extruder is part of the carriage, not a bowden setup)

But... I am a member of the Da Vinci group here on ThingiVerse, and they had a discusson on this issue. PEDMedia posted his fix: http://www.thingiverse.com/thing:1846161 - but I wondered if there was an easier way of doing this - IE by just using a new or longer PTFE tube with this 90 degree clip to bend it 'smoothly' to eliminate the kinking issue.

Let me know if it's viable and/or works. My aim was to come up with an easy fix that didn't require any hardware mods. ;-)

NOTE There are 4 different designs here - they are all based off the 180 degree PTFE tube clip from the SaintFlint extruder (here: http://www.thingiverse.com/thing:979113 ) - I didn't know how much 'bracing' would be necessary to maintain the 90 degree bend - so I created 4 different variants.

UNTESTED AS OF YET...
