Day 115 - Poly-Snaps Truncated Octahedron

Today we "truncate" yesterday's octahedron. Truncating basically means that we slice off the corners of the object. The result here is semi-regular, meaning that each face is one of two regular polygons and that the same configuration of polygons surrounds each vertex. This Truncated Octahedron is composed of six squares (each the result of slicing off one of the six vertices of the octahedron) and eight hexagons (each the result of the original eight triangular faces of the octahedron getting sliced off at each corner). Compare to the model of this polyhedron we made in Day 88 with the old snap-tiles; notice here that on each side we have the same number of snaps, whereas in the older model we had various 2- and 3-snap configurations on the edges of the square and hexagon faces.

Settings: MakerWare .3mm/low in two batches (to get the two colors).

Technical notes: After yesterday's fiddly tiles we return to the compact, sturdy tiles from the day before, with the Customizer settings below.
Sides = 4 and 6
Snaps = 3
Side Length = 25
Thickness = 3.5
Border = 3.5
Clearance = .17
Lengthen = .3
