About this model

When I started designing 3D parts, one of the first real challenges I faced was tolerance.On paper, two parts with identical dimensions should fit together. In reality… they don’t 😄 This model was created to measure precisely how much tolerance is needed for parts to fit together depending on your printer, filament, nozzle size, and print quality. The gauge includes:A 1 cm square insert and matching holes with tolerances from 0.0 mm to 1.0 mm, increasing by 0.1 mm each time.This allows you to quickly identify the perfect clearance for press-fit, snug-fit, or loose-fit parts on your printer. From my own experience:On a MakerBot Method, a comfortable fit started around 0.4 mm.On a Bambu Lab X1C, friction appears around 0.2 mm, and 0.1 mm can still work with light force.To go further, I also …
