This 3D model is a sturdy and reliable spool holder designed for standard 1 kg filament spools. It is specifically engineered to provide smooth and effortless rotation, which is especially important when printing with flexible materials such as TPU or Flex. The design helps prevent filament tugging, twisting, or jamming during printing, minimizing the risk of print defects or extrusion issues.

Ball Bearings: The holder uses two standard 6200ZZ ball bearings that ensure minimal rotational resistance, allowing the spool to spin freely even under low tension.

Compatibility: Suitable for most standard filament spools with a diameter of 200–235 mm, an inner hole of 40–57 mm, and up to 75 mm in width.
