In 1717, Abraham Sharp published an unusual little book which
describes twelve original polyhedra. The first and simplest of
his new "solid bodies" is an eighteen-sided form that I call the
"Sharpohedron". It consists of six rhombi and twelve
kite-shaped faces. Here are four versions of it: solid wood, paper,
assembled wood, and 3D-printed.
To make a paper or wood version, the following face templates and
net can be printed, cut out, and taped together. To make a
3D-printed version, use this STL file.
This video explains a bit about it:
I have written a paper about Abraham Sharp, Geometry Improv'd,
and the Sharpohedron:
