Disk Decoder Ring (Q62682)

If you like my work I hope you'll consider supporting me on Pateron: https://www.patreon.com/3DPrintingProfessor Subscribe to me on YouTube: https://www.youtube.com/user/mrjoesays Unlike my Caesar Cipher decoder ring ( http://www.thingiverse.com/thing:14891 ) this is a simple substitiution cyper. Based on the Ring-A-Thing. After making this I found a picture of the decoder rings from radio shows in days of yore. This isn't exactly like that. It works, tho to decode and encode messages like the one below. 2 5 19 21 18 5 20 15 4 18 9 14 11 25 15 21 18 15 22 1 12 20 9 14 5! EDIT: Added a facedown version of the letter disk without sloping inside and a blank version of the disk, also face down. It is left to the user to make a 2D printable letter disk to fill it with. EDIT: Added a png suitable for printing on paper and cutting out, possibly using http://www.thingiverse.com/thing:17645 . What it is not is scaled so the outter ring is 37mm across. Helping any way I can.
