Solved Ramps Fan Holder

The other day I went to work on my robo and I found that the 3d printed plastic fan holder that sits over my ramps board was broken, so the fan is no longer sitting directly below.

Does anyone know where I can find the 3d model that was used to print this? I have looked on thingiverse, but none of the models look like the one the printer came with. Since it's hanging upside down, I want to make sure it's snug and strong.

I have a second generation R1. It didn't come with a bottom cover.
