Vivedino/Formbot T-Rex 3.0 BMG Dragon Hotend Mod

thingiverse

I had some problems with the extruder and hotend of my T-Rex printer so i decided to change to a BMG Extruder and an Dragon Hotend. For assembling, you need to take of the "old" print head. I replaced a spacer from the carriage to hold the motor and the BMG exdruder. The Dragon hotend is mounted like the normal hotend. and the fan holder duct (call it what you want ;) ) is hold in place with the screws for the BMG/motor mount. I had to cut some screws to the right lengh. the upper left screw is about 37,5 and the two on the bottom are around 46mm but i can be plusminus 2. For the PCB you need a 10mm screw and some 6mm spacerin the back and in the front i but some m3 inserts in the print. I also put some M3 inserts in the print at the fan holder duct to hold the blower in place. This is still in progress and i did´t test it. But i´ll update and add more details for everthings as soon as possible.
