Ok, so here's my first fan mount for Wades Extruder with a J-Head Nozzle. (ok, second one - the first one went very wrong.. :) ) Ventilation for J-Heads body For 60mm fans It can be attached and removed without removing the nozzle, if you have enough length in your screws. Fits best if your Nozzle is mounted with an aluminum plate. Much improvements coming when I have the time, but this works and fits.
