I had a very hard time finding 30mm safety eyes for a baby yoda my wife was making so I decided to design and print them. I designed them to be printed in two halfs and glued together. these work very well and hold tight, so warning once they are on, unless you cut the back, they arent coming off, I also included an eyelet in the end of the post if you want a second means of securing them but it is definitly not necessary. I hope you enjoy! you can scale them as you need but if you get too small its likely to become fragile. If you would like another size let me know and as soon as I see the comment I will try and get it done.
