This model represents a custom impeller (fin assembly) designed for use in spinner flasks or other glassware, aimed at reducing shear forces during magnetic stirring. The part is intended to be used with a magnetic stir bar (6.7mm) inserted horizontaly in the central hole, allowing for smooth and efficient mixing while protecting sensitive cells or particles from high shear stress. Key features:two-winged fin design with rounded edges to promote gentle fluid movement.Central hollow column designed to house a standard magnetic stir bar, enabling magnetic rotation from below.Side support structure designed to be clipped or mounted onto a beaker (or similar glassware). Small notches provide multiple contact points for stable and secure positioning inside various container types.Printable in biocompatible or chemically resistant filament (e.g., PETG, PP, or medical-grade resin) depending on the intended use.Assembly Instructions:Insert a magnetic stir bar into the central horizontal hole.P
