English to Spanish Art/Literary Art, Arts & Crafts, Painting Mexican Art

I'm actually looking for an English-Spanish translation but the format doesn't allow me to look for it that way round. I'm translating an index for a book on Mexican art and in the index I have come across the term 'hail maker'. I have searched extensively on Google but have only found videos related to a kind of storm, which doesn't make any sense in this art or handicraft context, and just one entry, from a FB page, showing a kind of box or cube with illustrations on the outside. I have no idea if this is what the term in my translation refers to, it could be, it is related to art or handicrafts, but it is just one entry among thousands. Secondly, if it is the object referred to in the original text, I have no idea what it might be referred to in Spanish. A puzzle.
