Summary

Loved the original!
Wanted to make it a little more satisfying:
Made the spiral twice as tall, so the other slides up and down.

A few friends of mine preferred a small spiral in a double sized hourglass so I've added that too.
Saw a few requests for the originals in separate files so I'm adding them as a service, they of course belong to https://www.thingiverse.com/thing:6716355
