Update: The newly printed armor tiles turned out pretty well. Much better than the FIMO clay versions. Hate it or love it, this is a theme build, and I'm pretty happy with the results so far. The settings on the 3D printer weren't optimal, and there were some defects. Instead of just discarding them I decided to keep them and embrace the look of the damaged armor pieces. It provides a battle worn look that I can appreciate.
I created a template to align the placement of each armor tile before drilling holes. Placement was key, since I don't want to impede airflow and I want to avoid coming into contact with the CPU heat sink. In addition, I wanted the internal components to still be seen. The battle worn armor tiles are subset with the perfect tiles raised above to provide a 3D textured effect.
Unfortunately, the iPad bezel (version 7) had to be repainted, again. I'm waiting for the paint to cure right now.
I'll be out of town for the weekend. During this trip I'll be setting up a time and date, sometime next week, for the finalized photos of the build.
