PC Fan to 4" Duct adapter

This Model allows you to use a much cheaper 120mm computer fan as an inline extractor for your anycubic photon. You will need an existing duct adapter on your photon, some 4 inch ducting and duct clips, you then will print 2 of this model and attach them either side of a pc fan, creating an inline fan for your extractor set up. (you can power the PC fans by splicing the cables with the correct voltage mains adapter or a 9 volt battery).
