3D Printed Prototype Block Magnet

The 10x5x1mm rare earth block bar magnet has many potential uses in making 3D printed prototypes. Among them are:

• Snap-fit panels with magnets embedded in walls, lids or compartments create removable parts without hinges or fasteners. Pause printing at the desired layer, insert the magnet into a cavity, then resume printing to encase it. This produces a smooth, clean look where no screws or clips are visible.
   
• Modular prototypes (swappable parts) with interchangeable faces, modular mechanical assemblies, or electronics modules that snap together using the embedded magnets. 
   
• Hidden assembly points (invisible fastening) with magnets that attach covers, panels, or skins with no visible connectors. Simply print two matching parts with hidden cavities for the magnets to yield a clean finish that looks like a single solid piece.
   
• Movable joints or hinges (low-torque motion) where embedded magnets allow slight light rotational or sliding movement between two parts (rotating display bases, swinging doors). This simplifies the type of moving parts by not having to add springs or complex hinges.
