Little modular doll house I designed for my niece to make her love Sylvanian families. The furniture is not included and are not my work, other than the crappy bits, I'll add links to where I downloaded them. Printed in PLA. They sit together fairly securely, the floors can be rearranged and added to as desired. You could glue them together if you wanted to, but there's no need, adds to the play aspect to let them change the house around.
