This part is pretty simple now that I know how to print relatively well. I would suggest using PLA vs something like ABS because I've found that ABS warps too much especially as you get a larger print area for thing pieces such as this (if anyone has suggestions for fixing this i'm all ears). You can go up to very thick layers for this print, doesn't need to be nice and fine. I ran these at 0.2 mm per layer which was the highest Slic3r allowed me to go. As you can see I do not have a multi-material printer so for the tri-color tile I printed the orange separately.

For the orange I did have to use an xacto blade to shave off some of the edges to get it to fix, but it was overall very minimal.
