Single 4010 blower fan duct (untested)
thingiverse
This thing is possibly crap, but I'm posting it anyway just in case someone could maybe get a little bit of use out of it so my time spent designing it wouldn't be entirely wasted.I made this for my DIY printer but then switched to the fan being angled instead of 90°, so I haven't printed or tested this in any way (and needless to say, it's not flow optimized).I included the sketchup file so feel free to go to town modifying it :)
