In advance sorry for this terrible translation from Russian into English. It was not me - it's a translator from Google. For which he was a great thanks to him. Winter. In Russia, the winter is cold, so I have a warm pants with straps. But here's the rub! Broken buckle. My friend Mikhail Belyaev helped me get 3d printer Prusa Mendel, for which he three times, "Ku". So I decided to fix my pants, to make the buckle. It worked! Thank reprap! Thank budget prototyping!
