Geez! This keeps happening.
I've managed to find a few of the 3-D printing .stl files. Not for this one (which I believe you can purchase elsewhere for $19.99), but I have three [1] Metródōros at Athens Archaeological Museum, [2] Epíkouros at the British Museum, and [3] the Double with Epíkouros and Metrodorus from the Vatican. They're just under 150 MBs together, in case anyone has a 3-D printer.
I'd like to get one and experiment, but it's not in my cards at the moment.
