Keys for Electrical, Gas, Water Cabinets, etc.Triangle 7–11mm, Square 4–8mm + 2 Extra Keys I recently moved into a new apartment and, unfortunately, the landlord didn’t provide me with a key for the water valves. I borrowed one from a neighbor and, after measuring it with a caliper (triangle 11mm), I started searching for a suitable key. After browsing dozens of listings from Polish stores, AliExpress, and Temu, I couldn’t find the right one anywhere. I even started studying the standardization of these keys, but it turned out there basically isn’t any... So, I decided to design one myself. The triangular and square keys are slightly oversized — by about 0.1mm (at the narrowest point, due to rounding) up to 0.3mm — to compensate for any possible printer inaccuracies while still ensuring the key won’t slip. Additionally, the model includes two extra keys: Circural 2-pin and Stepped square — their dimensions are shown in one of the photos. I aimed to keep the overall diameter of the keys
