A new (small) product from us at E3D, a little direct extruder to bowden extruder adaptor.
Uses our little embedded couplings to make for a simple easy way to mount and secure bowden tubing to a printed extruder. Quite a bit nicer than forcibly screwing threaded couplers into printed holes.
Full drawings will be uploaded very shortly. Any and all feedback and suggestions welcome.
Shut up and take my money!
Forgot to link to the actual product - durrrr.

Huh. I seem to have independently come up with the same idea. Mine is printed with the collet heated and pressed into the plastic. 
Will these be available in the US via Filastruder?
Would love it if you could reply to support mail also Sanjay? Me and several others really need help with our V5’s http://forum.e3d-online.com/viewtopic.php?f=7&t=65&p=1570#p1570
Going to be trying out a v6 and was looking forward to trying it bowden if it works well; this part takes almost all the work out of trying it, nice work!
@Jens_Chr_Brynildsen Will do - the v5 forum has been escaping my gaze recently, apologies for the lack of responsiveness. If you’re having serious trouble please do get in touch on the “contact us” page on http://e3d-online.com
@Sanjay_Mortimer1 I’ve tried sending an email. Please get in touch. All the last posts on that thread are dismissing e3d for PLA. If it really works, we need to know. This is costing you business.
@Jens_Chr_Brynildsen I can confirm the v5 does work very well with PLA. There are a few small changes I have had to make, most are noted in the forum.
I have been watching the forum post for a while as I have at one time been defeated by the click click stick of PLA in a v5. I now have been running a v5 on one machine and a v6 on another, both on a .25 nozzle with PLA for over 130+ hours of printing; not suggesting running this nozzle size, just stating if this is possible about anything is. I have not performed a cold pull or cleaned the nozzles in this amount of time. Both are i3s on wade’s geared.
Things I will agree with: slowing retraction. On both machines the retraction is set around 400mm/s.
Seasoning the heartbreak, I fought this forever, but does work. I use canola oil at my burn temp. Dip the filament, extrude 100mm through, run my next print. I do this approximately every 15 hours of printing. I do not cold pull post, just run.
Set retraction a little below where it truly should be. I do post process parts more than I like due to small “hairs” running between printed parts. On a .4 nozzle I can avoid setting this so low… no post processing required due to proper retract setting.
A few things from my experience:
I am very strict on my extrusion temp. I.e, the small machine (V5) runs PLA at 172. At 180 it clogs, at 167 it clogs. This required a firmware change. The large machine (V6) runs at 181, 185 it has issues.
I run V6 nozzles on both.
I am no speed demon, typical to run at 55-60 mm/s, low acceleration.
I have reset the PID on both machines, I rarely get any temp fluctuation. Aim at a true steady state error of zero, “I” term.
The most important item on the V5/PLA list is an absolute perfect seal between the nozzle and the heat break. Any imperfection or crusted plastic on the surface between these two you will never be able to extrude for more than a few moments.
Hopefully something here will be of use and wish you the best of luck.
