Bought a set of Disney Princess Little People from Amazon. Packaging look legit, but the bases were different than the others we had (wonderful mount by W3asel https://www.printables.com/model/408437-little-people-mount/comments/1765209 for those) - anyway this mount I designed AND added to a Duplo 2x2 base by “sh”.
The fitment for different princes is different as for some reason they have slightly different bases, but all from my set go on, just some hold while others are loose.
The author remixed this model.
Added my https://www.printables.com/model/891864-fisher-price-little-people-round-mount to a 2x2 Duplo base based on “sh”'s Lego Duplo 2x2 brick half height Easy print.
