J-HEAD securer with 40mm fan. Wade's Extruder compatible.

This is a J-HEAD securer, with a 4cm fan support. The whole thing was made easy to assemble and remove. You'll need 30mm 3M for securing the j-head and of course the screw for the fan.
You also need to glue together the two parts of the fan.
Before print this thing make sure that the resistance of the extruder will not be in the way! :)
You may want to print the main part with 100% fill, obtaining a stronger holder.
It's not perfect, but I don't have the time to make it better, sorry!
