3D printing is my hobby – my officially recognized excuse to escape everyday life and build or rebuild completely useless, but damn cool models. Creative, technical, or totally useless: the main thing is that the printer purrs while I pretend to be "productive". With know-how, curiosity, and a lot of failures, I test, optimize, and fail – Learning by Filament! There’s only a standstill when the filament or coffee runs out… or when both have decided to rebel against me at the same time
