Rear cooling duct for PowerSpec 3D Pro and similar

thingiverse

This is a remix of the rear cooling duct for PowerSpec 3D Pro, FlashForge Creator Pro and similar Replicator clones with a couple enhancements. There were some comments that the supports were too thin, so I've beefed them up, particularly the ones that start on the bed. The clip that was suggested did not fit on the duct for me so I widened the connection and posted it as well. I printed it with some MadeSolid Pet+ filament I had and it printed nicely. The recommended screws were 3mm, but I found that #4 x 3/4" flat phillips wood screws (Hillman part #490001) worked for me to attach the fan. For the clip, #4-40 x 1/2" flat phillips Machine screws (Hillman part #491332) worked, though getting the nut in the opening was tricky - I had to clean it out a bit with a hobby knife and use pliers to squeeze it in there. I used these great instructions to get it all working: https://groups.google.com/forum/#!topic/flashforge/nuaE7yz1k7k
