Sovol dual 5015 cooling duct for Bondtech BMG-E3D V6

thingiverse

I upgraded my Sovol SV01 printer with a Bondtech BMG extruder and E3D V6 hot end. I designed this part's cooling duct so I could access the Bondtech filament tension lever and also see the nozzle as it was printing. I printed this in PETG with a 0.4mm nozzle and a line width of 0.48mm. When printing these parts, the back mounting bracket doesn't need any supports. The cooling duct does need supports in a few places. I included S3D photos showing where the supports need to be placed under the duct tips and the 5015 fan openings. I included three back plates. One has a mount for a TH3D EZABL Pro Mini, one is plain (no EZABL mount), and one is for a BLTouch probe. You will need some M3 screws to mount the back plate (and the cooling duct to the back plate). You also need four M4x25 screws and lock nuts to mount the 5015 fans. You do have to mount the 5015 fans (at least the left one) before you mount the cooling duct to the back mount. I added quick disconnects to my fans so they are easy to connect/disconnect. I didn't measure the M3 screws I used to mount the build plate, but I will update this with more detail on the screw lengths the next time I take off the cooling duct. I used three M3x10mm screws with washers to mount the cooling duct to the back plate. They just screw into the three holes and will self-tap. Don't over tighten them since they are going into plastic. Just tighten enough to hold the cooling ducts at the desired height. I have the bottom of the tips about 1mm above the nozzle tip. Also, if you use this with a TH3D EZABL Pro Mini, the probe offsets are +43 for the X and +5 for the Y. Edited August 12, 2020: I added two more files for mounting a BLTouch probe. I suggest that you print the small BLTouch mount with 100% infill since there are some areas with thinner walls. It will just add to the strength. Neither of these needs supports. Print as downloaded. You will need two M3 screws and flat washers. Edited August 29, 2020: Upon request, I added a file for mounting an 18mm probe.
