Prusa I3 3mm J-Head Bowden Mount
thingiverse
Updated the original design to match the current Prusa x-carriage mounting holes and for 3mm filament. Should be easy to add 1.75mm support as well if needed. I've verified things fit together as it should, but still waiting on my tubing to arrive so listing as a work in progress till I verify everything.

Instructions J-Head Mk V-BV:https://www.hotends.com/index.php?route=product/product&product_id=88 Fitting (1/4" BSPT, 6mm OD): http://www.amazon.com/gp/product/B004M8T26Y This doesn't use locknuts since they require more space than is really reasonable for this mount. Just heat up the fitting mount area (and/or fitting threads) and screw the fitting in slowly. That should create nice tight threads in the plastic and hold quite well.
