This is Airtripper's Bowden Extruder Modified to hold a push fit connector.


Purchase pushfit connectors: (one for your extruder body, and other optional one for the hotend)
See https://groups.google.com/forum/?fromgroups=#!topic/deltabot/LtLlZtANu4s for alternatives.

The units I purchased were less than $3.
MC KQ2S04-M5 PBT Push-To-Connect Tube Fitting, Hexagon Socket Head Adapter, 4 mm Tube OD x M5x0.8 Male

These push fits and other 3D printing accessories available here as well:

Also note: Jasper has an alternate one: http://www.thingiverse.com/thing:33342

Is this one built to take the MK7 drive gear?

Is this the 3mm version?, or the 1,75mm?

Gr nonaak

The connectors I specified are for 4mm hose, and the PFA tube I use it with has a 2mm ID, so this is for 1.75mm filament.  It is easy to adjust the hole in the SCAD file for different size connectors.

Thanks for the reply.

Can you give my a hint where i can chance the hole in SCAD?.
I m a totaly dummy in SCAD.

Hi, there's three lines with the comment, "tube and filament holes"

 #translate([4.8,37,15]) rotate([90,0,0]) cylinder(16, r=2.25, $fn=25);

translate([4.8,24,15]) rotate([90,0,0]) cylinder(20, r=1.5, $fn=25);

translate([5.3,10,15]) rotate([90,0,0]) cylinder(4, r1=0.4+1.0, r2=3+1, $fn=25);

You want to adjust the radii of these to use a different size connector.



I will give it a try.
