I updated this design and it can be found here Wish/specs/feature list: Update: I've edited the door, made it shorter and removed the grill as it is unnecessary and only hinders airflow anyway. Added it as a separate file. Update2: I've created a version for E3D v5's I design all holes 0.25mm bigger so it fits a screw right away, your results may vary. Please message me if you run into issues. The hotend fits very tight. Accompanying story: I've been running with my self made bowden coldend which holds a single E3D v6 hotend, a servomotor for a z-probe and a blower fan cooling the print. I am planning to go for a dual E3D bowden setup so it is time to design a new coldend. This time I wanted easier access to the hotend, have a better visual of the print as my current one has a fan shroud at the front cooling the print. I'm thinking whether to keep the z-probe servo as I had issues with it oscillating. I've already ditched the bed leveling before printing as it's usually quite easy to align the bed so I might as well ditch the whole servo.
