Maylan M200 Tower Grommet

I am pretty new to the 3D printing world. I was making some bowden tube clips and dropped one down the hole in the top of the tower on my Maylan M200. So I decided it needed a cap over the hole. I couldn't find one anywhere, but found the Customizable Oval Grommet by forswear_fopdoodle here https://www.thingiverse.com/thing:2820714 and decided to remix it. I added a top and a cutout for the wires. After the 5th try it fit perfectly on the M200, but there was a screw in the way of the edge of the grommet on the MPSMv2. I just sanded it down to fit on mine, but I am testing another print for it. Since this is my first post I am hoping I did it correctly.

Edit 3/21/2018: Uploaded v3, slightly larger so it fits the hole better.
