Ender 3 V2 | Dragon Hotend | BMG Direct | BLTouch | Remix

thingiverse

*Update: Added part cooling fan mount for 40x10 Noctua Fan. I'm using it with an DC-DC step-down voltage regulator at 24V down to => 16V 16V is feeling about the same as the default part cooling fan at 100% speed) Yes it is not good for the fan itself so it's lifetime could be cut but it is a looot quieter than the stock part cooling fan. Generally I have exchanged all the fans for the silent noctua fans and have achieved +-40dB loudness. /////////////////////////////// This is a mount for the Phaetus Dragon Hotend remixed from the other 2 things to match the Ender 3 V2 and the Dragon Hotend in direct drive mode with BLTouch and BMG (I used clone) extruder. Works very fine for me with the stock fans and you are able to use the stock extruder motor aswell. Hotend-Holder are making it possible to exchange the nozzles on hot without further tools. Mount was printed with PETG, printing with PETG and PLA without problems, haven't tried out with other materials, but you can freely put the nozzle fan duct off for materials that are not require fans if you wish. Nozzle fan duct and BLTouch height are adjustable if you want to play with it. The backside is modeled to get a threaded insert (M3) soldered in, to be screwed to the backside plate of the stock Ender 3V2 plate (like this one's): https://www.amazon.de/gp/product/B08BCSSKY1 But if you wish you can leave it just with the one screw on the front, it would work anyway ¯\_(ツ)_/¯ just have in mind that the BMG Extruder may affect it a tiny higher or lower depending of the stock mounts for the hotend screws on the backplate during the retractions. BLtouch do not interrapt with the nozzle fan duct, they are just close to each other. My wiring is not perfect but you can make it nicer ;) It is modeled to fit the same nozzle height as the stock ender 3 V2 Hotend so no really hotbed height affected or have to be adjust. It is just a bit moved forward so you would need to adjust the Z movement for the bed, I made it easy with some tape around the Z switch arm :D P.S. In my case the fan duct (at least the first one) is not printed quite straight even if the model is correct, so be aware, a bit height adjustment on some side may be required. P.S.S. Also be aware that you have to put out the tube fixing ring of the dragon hotend mount to be able to connect it with the BMG extruder and you should anyway insert a piece of tube inside the hotend and BMG Extruder so the filament can freely move threw them into the heatbreak withouth stuck somewhere on the way. In overall it's not the most beautiful thing but it's overall functionality is good in my opinion. Assembly: 1) Solder the thread insert into the mount 2) Put the Dragon Hotend into the BMG Extruder 3) Fit them into the Hotend Mount. 4) Screw the motor with the BMG together 5) Put the Hotend Holder inside 6) Put the Thermistor and Heater into the Dragon Hotend Plate 7) Screw the Mount to the X Axe's Backplate 8) Screw the Hotend Fan 9) Screw the Nozzle Duct Fan to the Duct mount (using M2 screws and nuts) 10) Put the Fan Duct into the grooves on the Hotend-Mount and level it right 11) Mount the BLTouch 12) Enjoy printing :) Well, I know, the hotend holder are modeled as one-way insert, but if you need... You can mount off the hotend fan and you would be able to use long nose pliers to push it back out, use same pilers to push the other holder from other side. If you also wish to exchange your fans, you could find used by me mounts here: https://www.thingiverse.com/thing:4612023 https://www.thingiverse.com/thing:4601320 Well I guess everything said, have fun :)
