Sorry for the title, I really dont know what is the exact term for that kind of keycap. It looks like this

But there is one part that I do not get. After the person made the base and the fnar figure (12:40) then he/she proceeded to put the whole thing inside a big mold and fill it with clear resin(13:57). The big mold kind of appear from nowhere to me, or did I miss something here? Because i think that the customed keycap is higher than a normal keycap (due to having a miniature inside) therefore the mold for the entire keycap can not be made with a regular keycap. Or can it? I cant really figure this part out, please help!!
