Davinci Hot End Bowden clamp

thingiverse

This is a simple Bowden clamp with an M6 internal thread ramp, designed to fit on the hot end of a Davinci. Once you take out the thread guide it goes straight in with an M8 (13mm) bolt to hold the bowden tube in place. I recommend sanding the last 10mm or so of the tube to get a good grip. Once you take off the existing feeder and associated gubbins it fits in perfectly, although It's quite tricky doing the clamp nut up when it is in place :( To be fair, this is really to see if it works (and it does https://youtu.be/jpV_-f8klWk ) consequently I have gone to a metal bowden fitting (actually the one in the picture) but you have to cut the end off the feed pipe to get that one to fit, whereas this one goes straight on. The second photo is with the metal bowden coupling. Note, getting rid of the extruder off the head saves nearly 400g, hence you can print a *lot* faster, you can also put a fan on the front which helps solidify things when you are printing that fast (100mm/s or 6000mm/min)
