Sometimes you just need a few extra inches to reach something or change a light bulb. This is  small sturdy step stool that will give you 220mm (about 9 inches) of boost. For strength, I printed this with PLA Tough, a 0.8mm nozzle, 3 walls and 15% infill. Used almost an entire spool of filament. Seems to hold 200lb easily, but make sure to test yours before stepping on it. It has been so useful I printed another one in white to match the kitchen.
