Romanesque D4

These are some 4-sided dice I designed a while ago and just got around to printing. I've stripped them off their supports, but haven't done any more cleanup than that so far.

I wanted them to look Roman-ish, so apart from using Roman numerals, I've tried to echo elements of Roman architecture in their shape.

They seem to roll adequately randomly, from what I've seen so far. I'm working now on refining some "baked in" supports (see below) so that I don't have to rely on Cura's occasionally inexplicable support placement.

They're a fraction more foot-friendly than the caltrop-tetrahedral d4s, but they've still got some pretty stabby points on them

There's a printable STL file available for download at https://www.thingiverse.com/thing:3115170 . The fin-like structures at the bottom are supports which will need to be stripped away after printing. I had to enable "Print thin walls" in Cura as they're only 0.4mm thick, and with my 0.4mm nozzle Cura wouldn't slice them reliably without that setting enabled.
