E3D V6 Dual Hotend and integrated layer fan - like the prusa i3

thingiverse

This modification is designed for E3D V6 dual extrusion use.\nThe nozzle offset is 32mm - I'm pretty sure that's different from the available modular x-axis-carriages.\nThe minimum required offset is 30.5mm - while my heatbreak requires a 31.0mm offset - and they touch each other! You can turn the hotend by 90 degrees.\nThe right fan duct is widened by 5mm because of the openbuild wheel's space needs. That's why I extended the airbox to the new fan's outer edge. To avoid collision with the x-axis extrusion profile, I shifted my hotends forward by 5mm - your x-axis carriage might need a modification if you experience any issues!\nIf spacing isn't an issue for you, you can use the normal part without the expansion - the airbox is identical to the left one.\nThere's also a small spacer and carriage for the SN04-N that I'd like to keep as close to my hotends as possible. The sensor height is adjustable without disassembling the hotends.\nI don't plan to edit these parts, but I'm not ruling out the possibility of needing to later on. I've prepared my own version of a dual E3D V6 conversion for future use - right now, I'm still running with the dual chimera extruder.\nI made a bridge to the modular x-axis-carriage using thingirob's design.\nCheck out this link: http://www.thingiverse.com/thing:2265140\nUpdate 2017-04-23:\nThe integrated fans hex-nut is higher than the pocket allowed - it was originally 2.25mm, now it's 3.25mm.\nThe old version would fit with a low-profile hex nut (DIN 439 / ISO 4035), but the current version fits with a standard M4 nut.\nI fixed the right airbox due to a mismatch - a small area was 1mm too high.\n2017-09-14\nWhoa, attention!\nThe fan wouldn't crash into the acrylic, but now it's got a problem with the upper v-slot wheel of the z-axis.\nThis depends on your printer, of course. With a stock tarantula, for example, I edited the modular x-carriage module to lower the full setup by 4mm down to bed.\nCustom Section:\nCheck out the settings with the tevo acrylic part - the fan would crash into the acrylic in this case, and you'd need to move the carriage at least 3.5mm forward - a modification I'd apply to the modular carriage.\nOn printers with steel rods instead of extrusion profiles, it's likely to be very different from the tevo tarantula example and will fit without modifications.\nTake a look at the image below:\nBecause of the resulting issue on my tevo tarantula, I moved the carriage that holds the 2 E3DV6 hotends forward by 4mm.\nThe next problem is the screw that holds the fan - replace the M4x18 with an M4x18 screw and a low-profile head for about 1.3mm.\nFinally, the working area of the heated bed in x-axis is reduced to something around 174-177 mm in dual extrusion mode.\nThe shift of the hotend so much on the y-axis - I'll have to figure that out.\nCustom Section:\nInterested and already got the modular x carriage from thingirob?
