Is this one built to take the MK7 drive gear?

rrhb - in reply to smolkd

yes.

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

rrhb - in reply to 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.

Thanks

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.
