Description
Springs grip a single card or up to 10 or 15. Set a pause at 6mm height and insert large washers for weight if you want extra heft (there are two voids, 32mm dia by 5mm thick), though the base is heavy enough not to be too much of an issue by itself.
Print 2 each of the two types of spring, and 2 of the bars.
Snaps together. Note the pins on the base are two different sizes. Assemble so that the lower curves curve towards each other and the tops of the springs are only 5mm or so apart.
