Notes A bit of trail & error is involved with finding a suitable fan combination for the Prusa i3 we have @ 'The Edge' - this page documents the process. We found the original setup as posted ( link ? ) was insufficient in cooling the object & were getting bad prints, hence seeking a better solution. Some of these parts may also work for other types of printers ... Edits : Trail printed some of the mounting brackets & found they were not quite working, so have added a longer version. Repaired holes in the *.stl file & uploaded them ... Added a few more details & photos ... Reworked Fan Duct added ... Cheers, Bantum ...
