E3D V6 - Double Fan Duct (Push Pull)

thingiverse

Double Fan Duct for E3DV6 Heatsink (Push Pull Method) - Enhances Cooling on the E3DV6 Heatsink and Barrel (and PTFE if not using All Metal). The reason I designed this was to boost cooling in a E3D V6 + All metal barrel + Volcano Hotend; all of them clones (by Trianglelab). I wanted to be able to print with PLA with this configuration, because I was experiencing constant clogs that seemed to occur just before the filament entered the Volcano Nozzle, inside the heater block (After a couple of minutes of printing, extruding stopped or the extruder stepper started to skip steps). After numerous trial and error attempts and a lot of effort trying to print with PLA (Plus extensive reading of forums discussing this problem and similar), my conclusion is: DON'T PRINT WITH PLA IF YOU HAVE AN ALL METAL BARREL (At least don't if you own a Clone, but I've read that many owners of original E3Ds have the same problem or similar). So... The Improved cooling on the Heatsink wasn't enough to prevent PLA from clogging... I switched to PETG and I'm printing flawlessly so far. If I want to print with PLA again, I'll have to switch to a PTFE inner barrel. Please comment if you succeed in printing with PLA using an E3DV6 + All metal Barrel, Clone or original. P.D: You'll need at least 4 M3x20mm bolts. - Remember installing one 30x30 fan "pushing" air into the HS and the other "pulling" air from it.
