Tronxy E3D V6 Holder with part cooling mount

thingiverse

I see lots of E3D V6 adapters for Tronxy but none of them had a part cooling fan, so I made one using Catia. It's designed for my Chinese replica V6 and has been a workhorse with over 200 hours of printing without any sign of heat distortion. I'm confident it'll work for you if properly mounted. The mount requires four M3 nuts and screws for the clamp and fan, and I highly suggest adding spacers. My first version had slots to drop in the nuts and screw but the PLA kept cracking under pressure, so this version requires pressing two nuts into place on the back. The mounting holes are for M4 screws of the radial fan, but I recommend using some M3 to give you extra wiggle room. The duct is a result of multiple iterations and the one present is the most effective one I've found. Knowing that I worked with a CAD of the full assembly, I allowed myself only a 1mm gap in the Z axis between the nozzle tip and the duct. It's press-fitted into the fan and doesn't need glue. My stock fan had a broken wire, so I replaced it with a blower to improve cooling and drilled some holes in the plastic clip using the E3D V6 Blower Fan adapter by matt448 (https://www.thingiverse.com/thing:1600018). I have to warn that my adapter shifts the hot end forward by about 5mm, so I've designed an endstop bracket due to time constraints because of school. You might need to trim some tensioners if you want full 150mm in the Y axis. So far, this hasn't caused any problems. I used an exact CAD model of a E3D V6 with tight fit tolerances, but you may need to file a little bit to insert it. Future considerations include shifting the hotend backward to eliminate the 5mm shift, adding a part to attach a cable chain for my next update, moving the radial fan bracket higher for more flexibility in the cooling duct, and making a version for a normal fan instead of a blower fan. Blower fans are good for high air volume, but normal radial fans can build up pressure better, allowing for both-sided cooling ducts.
