Summary

title says it all.
the feet were broken on the fan and I got tired of it falling backwards so I copied the pieces that I had.
I printed with ABS 0.4mm nozzle, 0.2mm layer height.
I built in some support but with abs it fused a little bit, it would have been better with PLA probably.
either way it worked well, fan is nice and stable now.
(forgive the Z wobble in my pics)
