My printer: Creality K1 Max 25 old self-taught mechanic and tinkerer of all sorts. I mainly work with cars, motorcycles, mopeds & computers. I finished high school in 2019 with specials in math, physics, and chemistry, and have since begun studying for a Master in Mechanical engineering. I make small batches of spare parts for hardware that is otherwise impossible to purchase. It's better to fix, when possible than buy new E.g I made a small retainer clip for a vacuum cleaner so I didn't have to throw it out, as the vacuum cleaner itself had no other flaws.
