While installing my Hydra Cooling System on my Ender 5+, the 5015 fans collided with the Y-Axis wheels before triggering the X-axis limit switch.  Measured and put this together real quick in Tinkercad, well…  real quick for me anyway.

Printed with 3 walls, 20% infill.  Not too complicated.  Filament is ZiRui Purple Glitter glowing PETG.  Not a lot of stress on the part so I imagine PLA might work.
