fan adapter rings for cabinet extraction

prusaprinters

these fan ring adapters fit into a 127mm hole which will cover a 120mm fan if you have made a printer cabinet and would like to use the exhaust holes from the fans for extraction whilst using fume producing filaments these are suitable for adaptation with exhaust ducting with a 127mm external and 120mm internal diameters the ring it's self is 12mm in depth which will happily sit into a 12mm sheet of MDF or plywood the four holes are either to help attach to a exhaust duct of your choice or straight to your cabinet build these are not modelled to be attached directly to a fan as the flange is too thin for this
