to make a dome, you'll need 26 connectors (20 hexagons and 6 pentagons) and 65 struts (35 of length A and 30 of length B).
to make a sphere, you'll need only six more pentagons (for a total of 32 connectors) and 60 each of strut lengths A and B.
this design uses 10mm holes that fit 3/8" hardwood dowels quite nicely, but feel free to adjust the script to your liking. to determine your strut lengths, use a calculator:
and refer to this diagram for assembly:
A 11.3 mm 35x
B 10 mm 30x
