This is a 2inch (~50mm) and 3inch (~75mm) hemispherical dome used for shaping EVA foam, based on Evil Ted Smith's video from 2016 (https://www.youtube.com/watch?v=6DVUlJ8JJzY). In his video, Evil Ted uses acrylic domes of the kind used for making bath bombs and the like, but I couldn't find that were easily available where I live, so I decided to make my own instead.I've built in a support for a standard 1" (~25mm) round dowel to hold the anvil.

Because this is half a sphere, you may be able to get away without using supports, but I used them in the centre of the sphere, just in case.
Smoothing
You may find the 3D printed texture keeps catching the foam and stops it slipping over the anvil smoothly. I found that a couple of coats of filler primer and then a couple of coats of gloss varnish were enough to help with that, although YMMV and you might find that your anvil works fine straight off the printer.
