Construct a circle of the desired diameter and draw concentric
circles within it to subdivide it into ten rings of equal width. If R is the radius of the net, the radius of the nth ring from the center is r_{n} = nR/10. Also divide the figure into 60degree sectors as shown. 

For the highest possible accuracy, divide the nth ring in each
sector into n equal arcs. The angles a will be given by a_{n} =
60i/n, where i ranges from 1 to 6n. The second ring out is divided at 30
degree intervals (60/2), the third at 20 degree intervals (60/3), and so
on. However, a tolerably good construction is to bisect each sector (light blue lines). From each even numbered ring construct lines parallel to the sector boundaries (red lines). 

Construct the short diagonals of each box.
