When applying for a university in the US, one needs to forward ones transcript from high school. There are two rules governing this:
Individually, both these rules make perfect sense. But together they conflict rather badly. How can one get a notarized translation when one can't unseal the envelope?
Fortunately the security offered by a sealed envelope is pretty weak and is relatively easy to circumvent. I sketched out a plausible pattern in Inkscape, extruded it in Sketchup, rendered it as G-code, then 3D printed it and glued it to a wooden handle. This enabled the creation of a pretty convincing wax seal.
The heat from the molten wax did not appear to have any adverse effect on the 3D printed thermoplastic. However I did find out the hard way that the stamp requires lubrication, or else the wax binds to the stamp and pulls away in fragments. Painting the stamp with coconut oil worked nicely.
3D printing is definitely a viable option for making a custom wax seal.
