Here are my Death Star plans that I had 3D printed at the start of the year.
The datacard isn't 100% accurate due to me modelling it before we had access to any decent reference material, but I'm still fairly happy with how it turned out.
BTW, the circuit board patterns were etched into the datacard by hand a couple of months after this was made, as I designed the model and had it printed long before any decent images emerged.
Thanks! I haven't gotten around to making a proper display yet, but it looks good on the shelf next to my half-finished Star Destroyer Capacitor.
I'm planning on making the datatape (also from Rogue One) and Dooku's plans from AoTC so that I can create a "History of the Death Star Plans"-type display.
