This Star of David has an internal space to embed a magnet while printing. It's a practical decoration for the holidays or any other time of the year, and the magnet won't ever fall out.
Design features
The model is about 43 mm point to opposite point, which should pass the small parts test for children under 3 years old (please supervise your children and use your judgment at all times).
The magnet is fully embedded and can't be removed (safer than a glued-on magnet).
Chamfered and rounded edges for easy handling.
When printing in flex filament it will hurt less when thrown.
I've rendered it for a reasonable 6x3mm or a ridiculous 15x10mm magnet. Message me if you'd like any other sizes.
The 15x10mm magnet configuration (with a N52 neodymium one) holds up cardstock to drywall screws. Also makes a good stud finder.
Message me if you'd like a different size.
Printing instructions
Choose the version you want (magnet size).
I recommend flex with 10% infill. (I used 20% for the glow in the dark filament.)
Slice the .stl file to include a pause after the magnet cavity (around 4.2mm/14.4 mm, depending on your layer height and which magnet size you're using).
Insert the magnet during the pause (glue isn't necessary for flex material, but if you're using something hard it will prevent rattles). Check that the magnet orientation is suitable for your use.
Note: The .gcode file I've included has a custom pause algorithm. Upon resume it will extrude a bit and begin a 4 second move to give you time to wipe excess material.
Safety notes
Magnets can be dangerous.
Please supervise your children at all times.
Notes
I designed this model in OpenSCAD and it's fully parameterized. If you'd like a simple modification (i.e., magnet size, outer diameter, height), send me a message and I'll see what I can do.
