Pentabolo Models

Pentabolo models five times as wide need only 25 pieces. Five pieces are remaining and the construction isn't hard to find for a computer program. Smaller models with scale factors 3*sqrt(2), 4, 3, 2*sqrt(2) and 2 using 18, 16, 9, 8, 4 pieces respectively are possible too, but not shown here The sqrt(2) enlargement fails for 5 out of 30 pentaboloes.
