Hard Drive Mirror Mount

I've wanted to design my own print for a while but didn't know what I wanted to make. After taking apart a 3.5" hard drive and seeing the shiny data disk, I thought to myself "that would make a nice mirror." Thus began this project. Using a ruler, I made measurements of the disk itself and the mounting mechanism it used. Then I used Fusion 360 to design my print, and printed it on my Ender 3. There is one flaw that I plan to revise (I don't know when). I designed the mounting holes too small, so I just took (I believe this is the correct size I used ) a 1/64" drill bit and drilled the holes out a little bit.
