I think the extension springs are going to work. I worked for a while on options to use compression springs and captured nuts, but they were all bulky to get the needed strength. The M3x50 screws were hard to get anyway.

Clough42, what file type is your dual belted extruder designed with? It looks like you are a fan of Solid-Works. I wish this was done in OpenScad.
I guess that kills it for me, and anyone else who doesn't use the hexagon hotend. Unless the hexagon stuff is optional, that is...
I'd still love a parametric hotend cooling shroud like your design so I could make it work with my E3D v6. Then I might be able to find a print cooling fan that fits.
Just guessing but there could be room for e3d v6's as well. Was there a dimension on the center to center of the nozzles?
The E3D v6 will fit if the centre-centre distance is 30mm or more. That's with fan duct installed as well, to have room for the 30mm fan. http://files.e3d-online.com/v6/Drawings/V6-175.pdf
Quick edit :). Yes, I was referring to the center to center on the extruder.
the fans can be rotated out some due to the clip on shrouds, so I think it could be less than the full 30mm.
Not very much, though, as there's only about 65mm in between the two side pieces bracing the extruder shelf. Less, if you have an ABL servo. It's going to be tight.
N.B.: I am in no way trying to nitpick or naysay clough42's design. I want to see it released so that I can use it myself. I'm sure any of these minor issues can be resolved or worked around in some way. I'll get different hotends if I have to, dammit. :)
I think it is unfortunate it wasn't done in OpenScad. That would have worked better for me.
