This awesome and simple fidget toy just needs a spring! Use BB003 OR BB005 from Maker's Supply OR just a spring from an old pen! And it prints in under 10 minutes! Please let me know if you need files for any other size spring. I'd love to make them for you!
Just put the spring into the button, and snap the button into the base. It can be a bit tough to snap it in, but this ensures that it won't fall apart. For the square you may want to use a bit of hot glue to secure the spring. The two pieces can be separated, however it is difficult. If the spring detaches, you may just need to print a new one.
