I loved the cute penguin drawer designed by chendragon2099, but I didn't want the drawer going all the way through the penguin. So I did a whole bunch of tinkering in Autodesk Fusion 360, closing off the hole in the back, making small cutouts in the front for gripping the drawer, and adjusting the drawer accordingly. I think it turned out beautifully! (It was a perfect anniversary present for my fiancée, who loves penguins.)
I recommend printing this in two batches:
Print A: "Penguin - Belly.stl"
Print B: Everything else.
Make sure you print everything at the same scale. And watch out for the beak, it's pretty sharp!
These files are optimized for printing on a multimaterial printer such as the Prusa i3 Mk2 MMU. Print it with a wide enough purge tower so that the colors don't mix too much when it gets to the penguin's face.
Not sure why, but Slic3rPE added some little loops of support above the eyes, so in some of the pictures it looks like it has eyebrows. They peeled off easily.
