Fixing E3D v5 hotend

thingiverse

After troubleshooting, I discovered that my prints were consistently bending on one side due to a 10-degree temperature difference between the "bad" and "good" sides of my bed. The culprit? My E3D hotend's fan, which was causing uneven cooling. To fix this issue, I simply redirected the airflow upwards, eliminating the problem of one-sided bent prints. This solution applies to my E3D v5 hotend installed on a RepRap/Mendel90 and was designed using SketchUp.
