@sinituulia @laumapret (I've seen a tutorial on making one yourself¹ with insulation foam that can be pinned into, but my first attempt to make a mannequin of my foot² didn't work that well, I need to try other foams.)
(and of course, I haven't tackled the stand issues yet)
¹ for values of yourself that definitely require another person to wrap you in plaster bandages
² mostly as a small scale test, but it can be useful while making socks and slippers
