Expensive but rock solid. I saw this button maker repeatedly recommended by public libraries. I bought for use in our school makerspace and it is a great starter project. Every kid can leave with something they designed and made in the same class period. Check out ideas for using in a school makerspace. https://designmaketeach.com/2017/02/15/making-the-buttons/
The Busy Beaver Button Museum has a fantastic set of photos of historical buttons to inspire your designs.
