Makerbot 12cm Exhaust Fan Adapt
thingiverse
This thing adapts a standard 12cm PC fan to a standard 4" exhaust / vent duct (available a Lowes or HD). This allows smooth flow of fumes to wherever you like (outside). Instructions Once again, I had this all typed out and lost it when I uploaded pic. Crap. Basically, print out thing 4 times, cut/trim excess plastic and/or raft. Screw pieces to standard 12cm fan (120mm). Seal part gaps with hot glue (recommended). Connect other side of fan to a board (cardboard for me), and attach to side of makerbot. Be sure to enclose the box a much as possible (I leave the front of mine open for good air flow) Now I can print 24/7 without having to worry about inhaling fumes.
