He bought a printer and started experimenting seriously. \n At a certain point, the first requests arrived: a broken part to replace, a spare part that cannot be found, a handy adapter to have. The requests increased and we said: okay, let's do it properly.\nLater we created a calculator to understand the cost in advance: it was one of the first steps that took us from \"let's make a few parts\" to a real project, together.",
