I've been thinking of building a tube fin rocket. The obvious solution is six of something around itself.
Why be obvious? I was wondering if there were any combinations of the tubes out there that would line up perfectly with four, five, seven, etc tube fins. There seems to be no spreadsheet for this, so I made one with common tube sizes from 13mm to 5.5".
Left side is center tube, top is fin tube. Cells are highlighted if the number of tubes is within 0.05 of 4, 5, 7, 8, 9, 10. More than 10 and you barely have any fins. 6 is not highlighted for obvious reasons.
