This is a yarn spinner/holder with a space that you can either use to store stuff, or to fill with something that gives it weight! I use a bag with beans, so it stays steady in place.
Printing: The parts don't require support when printing, but I recommend to print the Pin part horizontally (and with support, if so), as after some tests I found it easy to break when printing vertically, because of the layers position.
