Code Wheel Free 3D print model

My dad showed me this cipher when I was a kid, and I've wanted for ages to make a printable code wheel that would allow others to learn the cipher. This is some sort of variant on the Vigenere cipher but I'm not sure of the actual name of this variant, so if anybody knows, please let me know in the comments! I know it's also related to the key autokey and Alberti ciphers. In addition, I have a prize for the first person to correctly decrypt the ciphertext below and post the plaintext to the comments... I loved the steganography challenge in the Seej block, and it's high time we had another contest... Good luck! You'll find that brute force is not the way to go... there are 1.243841e 142 possible keys. There is now a monocase alphas only ciphertext of the same plaintext, which reduces your keyspace down to 4.0329146e 26 possible keys. Keep in mind that an attacker doesn't need to do an exhaustive search of all these keys; once he has some of the letters right, they will help him get more letters right, and the effect will snowball until he has the entire key. Indeed, I cracked the alphas only version by hand in less than 2 hours. This algorithm should therefore not be used for anything that you actually need to keep secret.
