I’ve been working on a modification to the new V2 toolhead to allow ninjaflex printing with parts from a flexystruder. First, I disassembled both toolheads and discovered I would need a spacer to allow tight enough fit between the hex head intake end and the flexystruder body. I designed one that works fairly well and is available here [http://www.thingiverse.com/thing:714247](http://www.thingiverse.com/thing:714247). I assembled the hex head with the stock aluminum bracket and then slipped the spacer onto the hex as shown. Next I loaded a length of ninjaflex into the flexystruder and turned the gear manually until about 15mm of filament was exposed. I lined the filament up with the intake hole of the hex head. I had to get new 25mm mounting screws as the stock ones were not long enough. Finally, I tighter everything up. I mounted it as usual, primed it, and went ahead with a test print. So far so good… The stock flexystruder has a 0.5mm nozzle while the hex has a 0.35. I changed my Cura profile accordingly. Further tests underway… ![IMG_6455.jpg](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/1/1b6b8ed6b6b8efff7ed9e6853683f3e65cdd2370.jpeg) ![IMG_6456.jpg](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/a/a437cd68d643a17e380595a05cf2b26095e78ae6.jpeg) ![IMG_6457.jpg](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/a/a7f9495fb01f7e93cc7d8d5b1c1f18565c5866f6.jpeg) ![IMG_6458.jpg](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/7/7a9983cbd910a615f5ebf55f3819773c92d30f12.jpeg) --- _[View the full topic](https://forum.lulzbot.com/t/hex-hotend-toolhead-v2-flexystruder-modification/1413)._
