Description
Build a repeatable curved magnet array without hand-aligning dozens of individual magnets. This David LaPoint-inspired printable fixture contains 36 angled seats arranged in four bands across a compact hemispherical holder. The modeled seat axes converge closely toward a common geometric region near the open side of the bowl, giving builders a consistent physical platform for studying how magnet position, angle, spacing, and polarity affect the combined field.
Physical value and purpose
The value of this design is mechanical repeatability. A loose magnet arrangement can shift during testing, making measurements difficult to compare. This one-piece holder fixes the geometry so a builder can change one experimental variable at a time, document the polarity map, return a sensor to the same location, and reproduce the setup later.
Practical uses include:
- Mapping field direction and relative strength with a Hall sensor or gaussmeter
- Comparing common-pole and alternating-polarity arrangements
- Demonstrating attraction, repulsion, symmetry, and distance effects
- Positioning a compass or probe near the central geometric region
- Creating repeatable classroom, workshop, and builder-lab experiments
- Photographing and documenting a known 36-position array
Verified model details
- One printable watertight STL
- 36 angled magnet seats in four curved bands
- Nominal 10 mm magnet format
- Approximately 9.77 mm modeled seat openings
- Approximately 6.73 mm modeled seat depth
- Overall size approximately 81.19 x 81.20 x 37.54 mm
- 35,686 triangles
- One connected manifold body with no detected boundary or nonmanifold edges
- Central opening for potential probe or visual access
Magnet fit
The source identifies this as a 1 cm magnet array. Because the modeled opening is approximately 9.77 mm, a nominal 10 mm magnet may fit tightly after printing. Magnet diameter, coating, filament shrinkage, flow, and printer hole accuracy all matter. Measure your magnets, calibrate dimensional accuracy, and dry-fit before applying adhesive. Do not force brittle magnets into undersized seats.

Important experimental notice
This holder arranges ordinary permanent dipole magnets; it does not establish a verified magnetic monopole. No magnetic-monopole, free-energy, over-unity, propulsion, gravity-modification, healing, or guaranteed electrical-output claim is made. Results depend on the magnets, polarity map, assembly accuracy, measurement distance, surrounding materials, and instrumentation.
Strong magnets can pinch skin, chip, shatter, damage electronics, and interfere with medical devices. Keep them away from children and pets, wear eye protection during assembly, and read the included safety guidance.
