I designed this from scratch in Fusion 360, matching @DecoPrint's dimensions. I wanted a version that I could easily assign colors to and print with the inlay in place using my X1 Carbon. The only other change I made from the original design was to make the insert ring slightly wider.
I have included versions of the model so that you can still print the stand and inlay ring separately (with 0.20mm clearance) and glued together later.
I have also included my Fusion 360 source file so you can easily remix it if you'd like to.
