Round Desk Fan for 120mm PC fan

thingiverse

I needed a quiet fan for my office so I made this to house a 120mm fan. The design is round to hide the fact that it actually uses a ugly PC fan. This is about the tightest fit possible to hide a fan of that size. The fan I used is a 20dB fan with 50cfm flow. It is barely audible and gives a gentle breeze. For the stand I used a polished 8mm steel rod I had left over from some other project. I suggest you use something similar as it looks very nice, perhaps wood or bamboo or even a drinking straw could work as the fan is very light. I included a printable rod in case you need one. The large rings have 175mm outside diameter.
