This is a russian nesting doll version of a ding ding. To make a ding ding fit, you need to either scale it up to 167%, or down to 60%. I'd recommend adding custom supports on and around the three points on the head where the bottom slots in, roughly as shown in a picture above, especially on bigger ones.
