Squishable Ace The Donut v2. Really fun to hold in your hand as a relaxation ball.
The new version has a redesigned bottom to make it easier to print and to remove support.
The walls are significantly thinner to make it more pleasing to squish and fidget with.
The beads are bit stingy. If you prefer a softer version, try the beadless version at makerworld.com/models/486622!
