This is a reproduction of the key used by Mr. Tumnus in The Lion, the Witch, and the Wardrobe. I'm hoping the representation is fairly accurate based on the images I have found on the internet.
There are two versions of the key depending on what works best for your printer. The version labelled full is a full key to be print at one time. I printed this one on it's side so I could get the details on the leaves to come out nice.
The second version has the leaves and the stem as separate pieces. This should allow you to print each piece with your desired level of infill. It also should make orienting the pieces a little easier.
I am in the process of making several more props from the Narnia films and books so be on the look out for many more to come.
