«3D Models of 20 mm Gears and Gear Mechanisms»
The models range from standalone gears with different tooth profiles to gear fidgets, motorized gearboxes, and calibration cubes. Some are designed as functional parts for mechanisms, while others are stress-relief toys or test prints for checking dimensional accuracy. Rail mounts and adapters that use 20 mm dimensions also appear, though they serve a different purpose.
When choosing a gear model, check the tooth count, module, and bore diameter on the author's page, as these determine how it fits with other parts. For motorized versions, review the required motor type and any assembly instructions. Also look at the recommended layer height and material, since small gears can be sensitive to print orientation and cooling.
To narrow your search, try synonyms like cog, pinion, or sprocket, and combine them with terms such as fidget, motorized, or calibration. Related topics include gearboxes, planetary gears, and rack-and-pinion systems. If you need a specific size, adding the diameter or tooth count to the query can help.
