Weibel–Palade Body Model

This is a simplified, artistic model of a Weibel–Palade body, a special organelle found in the cells lining our blood vessels. These bodies play a crucial role in processes like blood clotting by storing and releasing von Willebrand factor.

The model is designed in two halves that fit neatly together. It includes an internal cavity designed to hold 5x2mm circular magnets, allowing the two halves to snap together satisfyingly. This makes it a great educational tool, a unique piece of science art for your desk, or a fun fidget object.

Printing Instructions:

This model is designed to be printed with three key features for the best result: fuzzy skin, embedded magnets, and a color change.

Fuzzy Skin (Outer Texture):

• To achieve the textured, organic look seen in the photos, enable the 'Fuzzy Skin' feature in your slicer (available in PrusaSlicer, Cura, and others).
• It is highly recommended to apply this only to the outer walls. Use modifier meshes or your slicer's paint-on feature to ensure the internal surfaces and magnet holes remain smooth for a perfect fit.

Inserting Magnets (Pause Print):

• The model has internal holes designed for 5x2mm round magnets.
• In your slicer, add a pause command (e.g., M600 in PrusaSlicer) at the layer just before the roof of the magnet cavity is printed.
• During the pause, drop the magnets into the printed cavities.
• Crucially, ensure the magnet polarity is correct so that the two printed halves will attract each other. It's a good idea to double-check this before resuming the print.

Color Change for Lines:

• To achieve the highlighted stripes, you need to set a color change in your slicer.
• Set the color change to occur at the layer just before the lines on the top surface begin to print. This will print the main body in one color and the detailed lines in a contrasting color.
