The Barrel o octopus game has been a favourite in our house, and I have alot of random Octo's laying around the house - but they are all the square edged version and not suitable for hi res FDM printing printing or SLA and not suitable for large prints due to the low poly nature (which is great when printing a dozen out for a game! but no good for printing one big nice shiny smooth round one out) Sure, this takes a little longer to print but the end result is much better.
