Anyone made it in PLA and comment on heat/getting soft?

It worked well for me for months until it failed badly when my fan failed!
You will be safer with ABS, Nylon or XT. Nylon is a bit flexible, so not very good for precision.
PLA is much stiffer so it is a good choice if you can assume the risk of cooling failure (stiffer even is CFPLA, so I would guess that XT-CF is a winner here).

Cool, thanks :)

how is the head oriented? to the front left corner? front right? I can't tell from the pictures

The head vertical offset is to the back & left of the case when seen from the top (or reciprocally to the front-right is mounted the other way), cheers

How did you attached the pneumatic fitting on top of the E3D hotend - does it came threaded?

It came like this when you specifically ask for the "bowden extrusion" version -- see http://e3d-online.com/index.php?route=product/product&product_id=50http://e3d-online.com/index.ph...
I realise that my design would need some serious modification to hold a push fit by itself (in addition to the head).

Thanks. Do you have an URL/source for the pneumatic fitting?

Oh no, sorry. Actually I did not like the one that was provided anyway. It is a regular 6mm OD pushfit as far as I remember. You may check my blog on the matter: http://www.tridimake.com/2012/10/re-drilled-top-brass-quick-connector.htmlhttp://www.tridimake.com/2012/...

Great! Thanks for the reference! :) I just changed mine for a dumb blind rivet and filed it with such a thread (by guess, as I'm in a metric world here!)
