- --rot is three.js Euler XYZ (Rx*Ry*Rz), the order printfins.com shows under the part, so a pose found on the site carries over - --fins-only maps the fins back onto the part as it is in the file; it can't take --rot, and writes nothing when there are no fins - a Support Fins 3MF (part + fins) is refused instead of finned again - settings the site would hide warn on stderr; -o can't overwrite the input; -- ends the options; Node 20.10+ - the summary rounds ties to even, word for word with Python's host_report
