I searched for a dual or Singel Duct Fan for my Tronxy X5S with 5015 Blower but i only found for 40x40 axial or for the E3D so i remixed this one which is on my CR-10... It is hight variable for about 2 cm so might fit to an Vilcano but not testet.
You need some litte Support structures for the Cable Fix an the Holes which go trough the Hotendmount Plate... so nothing extreme...
can work with any cooling hot end mount, I sugest mine https://www.thingiverse.com/thing:2612897 is a fast snap mount so u can remove the cooling fan and adjust the fan mount without actually remove the metal hot end.
Hope you like it !
