D20 Ring - WIP (Read changelog)
Description
This is currently a work in progress, as I find that the printed numbers aren't easily readable. If I manage to solve the current issues, I will certainly make other versions with D6,8,10 and 12 rings. It is a fairly chunky ring but it spins and fits well. It's also very easy to construct and glue together! (Only put a little bit of glue on the outside of the innermost ring.) The ring size is around 19.48mm diameter or an US 9 and 5/8ths ring size. You can scale up the X and Y values to change the size to fit your hand better as follows: divide your ring size's by the size of the ring (e.g.: 15.20mm / 19.48mm = 0.78) then multiply that value by 100 (e.g.: 100 * 0.78 = 78) That value is the scaling factor for your X and Y (e.g.: 78% of original size for a ring 15.20mm in diameter.) So far, I have done some math that tells me the ring is a little biased (based on 200 spins), which means there are fewer 4,5,6 than there should be and more 12,13,14 than there should be. (around 10-15%). And this is also part of why I'm marking this a WIP. I would be very happy to have some help to figure out ways to reduce bias and make the spinner more fair.
