Wind tunnel!

thingiverse

This is the first wind tunnel on thingiverse, and many other 3d file sites for that matter! the wind tunnel is desktop size, single return, closed circuit, with a 70mm X 70mm test section. Made for Delta PFB1212UHE-F00 252 CFM fan(link). Great for science fairs, presentations, demonstrations, toys, and any other application that requires smooth air flow, but keep in mind the accuracy is not good enough for professional work! if you have any requests just leave a message! Instructions It is not recommended to print the assembled wind tunnel. The size should fit the 120mm fan specified. If it is way too small, multiply the size of all parts by 10. The tunnel requires lots of plastic material despite the thin walls, but the final product is worth it(if you bought it it would be hundreds of times more expensive!). The tunnel requires a Delta PFB1212UHE-F00 252 CFM fan, and an optional plexiglass cover for the test section, plus any other electronics and equipment that you may require. print one of each part except 2 turning piece connectors, and 4 turning pieces.
