Ninjaflex / Flexible Filament Adapter for Duplicator i3 V2

thingiverse

I've included some pictures of the ever popular twisted vase printed in ninjaflex after all the mods and with all the settings mentioned below. This is to show any skeptics that you can indeed print ninjaflex with perfect results on the Duplicator i3. I recently printed dokool's extruder plate located here http://www.thingiverse.com/thing:1340811. It makes a big difference, and I've gotten some pretty complicated prints after installing it in combination with my adapter. With the plate I printed at 20mm/s, 1.00 extrusion multiplier, 1 mm retraction, and an infill overlap of 35%. If you've already printed my adapter, I would definitely suggest printing the plate as well. This is an insert for the extruder so that Ninjaflex specifically will work. I don't see why it wouldn't work on other flexible filaments, but I've only tested Ninjaflex. The other piece is an adapter for the spool. The standard spool size of Ninjaflex is 2 inches and the Duplicator has a 1.25 "spool holder. To install the extruder insert, unscrew the large cooling fan and remove it and the heat sink. Lift the stepper motor up and place the insert with the large hole facing down. It should fit perfectly over the nipple on the extruder base. Definitely use ABS so it doesn't deform from the heat. I've been successful printing with Ninjaflex at 15mm/s speeds with the bed off and the extrusion speed at 60% with a 325% first layer height on buildtak. Also, I changed the infill overlap which was 15% on my settings to 30%.
