Behold, the squircle-oid!
This is the shape defined by the equation
$\left(\frac{x}{2}\right)^4 + y^4 + z^4 \leq 1$
I made it as part of a set of props for explaining Lᵖ norms. p=2 gives an ellipsoid, and in the limit p → ∞ you get a cuboid.

@christianp do you have a recommendation for a printer for a complete beginner (myself)?

@pkra the Flashforge Finder that we have is very easy to use, very reliable and cheap. It's ideal!

@christianp Thanks. It's on my wish list now 😇

@pkra 98 days until Christmas!
