This is a fume extractor i made one to save my lungs.
What you will need is a 140mm fan,9v adapter and to print the two STL-files.
you can purchase a
140mm fan here
The first part i used a support. the second part does not need support.
Infillrate: above 10% should be fine.
Note: if you want more flow, just add one more fan! but if think its good as it is.
