I've made some prints fit in my printer by printing them at a diagonal. I work it out by spinning it until I don't get an error from the slicer.

I'd rather be able to calculate exactly what will fit beforehand instead of spinning the model around in CAD or the slicer.

Has anyone found/used a calculator that can do this?

because 3D printers have their own constraints in things like the overhang that they can do.

That's what supports are for. :) In my case I made a custom sprue because autogen supports sagged unless it was 0 clearance.

I was just looking for something like a rectangular prism or cylinder to fit in a cube. I was surprised by the replies that it's mathematically hard. I expected it to be a geometry problem with a bit of calculus to find the convergence.
