Unimpressed with the stock radiator I looked for a suitable replacement. Found a couple but was not entirely happy still...
This design is a direct replacement for the stock part but also incorporates a cable harness holder with cable-tie holes.
UPDATE: added files for the accompanying cooler duct.
The design is for E3D v6 (originals or clones) hot-ends to replace the stock v5 variant.
Used my Ender-2 to print this in PETG for strength and heat resistance.
This is the 3rd and probably final version, utilising 2 x 40mm fans, M3 bolts and washers.
I have uploaded both the STL file and the Fusion360 archive file so you can easily start customizing it.
Print standing up as in the Fusion render pic. This makes sure the feet are perfectly flat for a good fit on the effector plate.
Make sure to remove all support internally as you don't want any plastic bits to make an annoying sound against the fans.
Designed in Fusion 360 using accurate measurements from the original stock part.
