printrite bowden feeder

design is for use with my printrite J-head adaption design,

both versions of the design shown have a filament exit hole suitable for a screw in 6mm push fit connector for either 6mm OD ptfe tube (3mm filament) or 4mm OD ptfe tube (for 1.75mm filament)

v.1 is designed for use with a mk7/8 extruder feeder (alternatively you can use 1sPiRe's own design - http://www.thingiverse.com/thing:1548736

v.2 is designed for use with the original printrite feeder (which saves additional purchase/printing of feeder setup but is less reliable as the mk7-8/1sPiRe type feeder

both designs have 2mm bolt holes for mounting to wherever you wish on your printers frame (or even away from the frame if you so wish) but the closer to the extruder the better as this will minimize flex in the ptfe feed tube running from bowden to extruder (which can effect retraction and cause a small degree of oozing if not addressed)

warning: use the correct tensioning arm on the design specified above, though bo
