height-adjustable holder for Anet A8 radial fan / filament cooler

thingiverse

After printing lots and lots of fan ducts and finding out that one is too short and cools the heat block down, another one is too long so it crashes into the heatbed, I decided to construct this thing to make the radial fan height-adjustable to use any fan duct I want. Assembly pretty much straight forward: - Drop a nut in each of the two shafts of the back piece, don't worry, it doesn't get lost - countersink the bore of the radial fan from the back side, the screw needs to fit in flat - screw the radial fan to the fan holder with the washers and two of the nuts - connect the two parts but don't tighten the screws completely - install it on your printer, put your favorite fan duct on and adjust the height, then tighten the screws carefully (not to tight, the back part could break when going too far ;)) Any ideas, questions, suggestions? Just comment. You made one? I'd love to see some pictures! :)
