We recently got the Little Tikes Cape Cottage Playhouse since we found it on clearance. The kid is happy with it, but I saw a lot of potential with the layout of the house and wanted to do a little something more.
The idea is that you'd print two of these, then slip them into opposite windows, then put a board across like a countertop. Realistically, you could probably split this model and add it to something like a cupholder, a flower pot, a coat hook… no shortage of things you could add.
I made it to look like a nice little windowsill with some simple trim along the bottom, which my kid uses to rest a rubber ducky on now that it's installed.
The author marked this model as their own original creation.
