Geeetech i3 Pro B - E3D Titan extruder support (with V6)

thingiverse

This is a vital upgrade for Geeetech i3 Pro B that enables the mounting of E3D Titan extruder with V6 hot end. I personally crafted this design, striving to keep it remarkably compact and incorporating a fan to cool filaments during printing. Currently, I'm working on another version that will support extra accessories such as BLTouch. To assemble this upgrade successfully: 1) Print the Titan support with the large backplate facing the printer plate. 2) The support features embedded M3 nuts for securing the 'fan tube'. If you're unfamiliar with embedding nuts, it's highly recommended to watch a tutorial video. Essentially, you'll need to edit your GCODE and insert a pause before the layer that encloses the nuts. My custom 'pause' script is provided below. 3) I strongly recommend printing the fan cooling part in ABS due to its proximity to the nozzle, which may cause it to bend. Script to pause for embedding nuts: G91 ; relative coordinates G1 Z10 ; move nozzle up 10mm G90 ; absolute coordinates G1 X0 Y180 F1000 ; move nozzle to X=0, Y=180 (adjust settings accordingly) M400 M300 S4000 P2000 ; play sound at 4000hz for 2000ms M0 Wait to proceed ; wait for instruction (some printers may require clicking "Continue" from Octoprint or display) G91 ; relative coordinates G1 Z-10 ; move nozzle down 10mm G90 ; absolute coordinates
