Would this work with a J-head?
I got these push-fittings:
Now discover that I maybe overpaid a bit on them..
How does the 3mm filament do in your Bowden? I am planning to build my MendelMax 1.5 in the next weeks and give it a vertical X-carriage and a Bowden setup :)

Use: Consider using a light lubricating oil spray in the bowden tube if you are having trouble with filament friction.
UPDATE 27/03/13: The larger pneumatic fitting creates a smaller collar on the Hotend Mount. I have added another file (v2) that will be stronger as a printed part. 2 more holes need to be drilled out.
UPDATE: 29/03/13: More generous sockets have been added to all three printable parts. The original sockets were very tight indeed. The larger sockets still grip well while also making assembly a lot easier.
Remixed Sketchup files included. Remix on!
