A friend asked for a holster to mount his O2COOL personal fan so that he could wear it clipped to his shirt while he was working. This was a quick toss together but it works well. It allows it to be hung from the shirt collar and still keeps the intake air path open. As an adder I wanted to tinker with the blower itself and popped off his original turbine blade and made one that was around the same weight but more effective with overall flow. No true measurement of cfm increase, but a noticeable flow increase just by feel. It has been in use for around 4 months and has had no issues. The blade was resin printed for accuracy reasons.

The PLA was what I had on hand, it should be ran in PETG or PLA+ for better heat resistance.
