The bowl stands at about a foot in height and, despite being very light, is sturdy and extremely well balanced so it won't topple over when filled.
You can now buy a kit for this bowl on the Instructables Store. We're making these ourselves at the Instructables Lab, so supply will be limited!
Step 1: Modeling the hand
When posing the hand, I had a few things to bear in mind. Obviously I wanted all of the fingertips to touch the ground at the same level so that the bowl would stand upright. I also had to think carefully about the way I splayed out the fingers. The fingers needed to provide as broad a base as possible while also looking natural and comfortable (Poser does nothing to stop you contorting its models into grotesque and unnatural positions, so this is trickier than you might expect).
A more subtle issue was to do with how I knew the model would eventually be sliced when I exported it into 123D Make. I knew from the outset that I wanted this bowl to made of radial slices converging somewhere around the base of the palm. This meant that I had to position the fingers so that they all roughly pointed straight outward from the same spot (so that each finger would contain a slice of plywood). Any major misalignment would make slicing the model impossible. This is an excellent example of how crucial it can be to visualize the entire design process of a project before you even start modeling.
