Solar System Magnets

Model Overview & Print Notes

A colorful set of Solar System magnets based on flat 2D vector graphics, converted to 3D using MakerLab Image to Keychain and further refined with custom OpenSCAD tools.   Each planet (and the Sun) is a separate 3MF file, and prints as a single, multi-color magnet. It can be used as decoration for fridges, and on classroom whiteboards, as a tool in teaching astronomy.   Planet diameter is ~50 mm.   Important The complete multicolor planet models are provided as Bambu Studio 3MF print profiles. The STL files contain only the optional magnet negatives, which were added afterwards for customizing the magnet pocket. The 3MF files were created using MakerLab Image to Keychain and are intended to be opened in Bambu Studio. Features Flat 2D style graphics Smooth, rounded outer edges (generated from custom OpenSCAD negative STL for circular and non-circular shapes) Parametric magnet pocket inside the 3MF Multi-color printing Great for decoration and gifts, and also as a learning tool Updates March 2026: Pluto has been added to the Solar System magnet set. Pluto, a dwarf planet, is 4 cm in diameter, while the major planets are 5 cm, and has the same rounded edges as the rest of the magnets.   May 2026: Other dwarf planets (Ceres, Eris, Haumea, Makemake) have been added to the Solar System magnet set. As dwarf planet Pluto they are 4 cm in diameter, and have the same rounded edges as the rest of the magnets. How it was made Original 2D flat planet graphics Converted to 3MF using MakerLab Image to Keychain Rounded-edge negative STL generated with OpenSCAD Magnet pocket added as a negative cylinder inside the 3MF This workflow keeps geometry clean while allowing easy customization. Customization IInside each Bambu Studio 3MF print profile you can: change magnet hole diameter change magnet hole depth move magnet pocket position if needed This allows compatibility with different magnet sizes and thicknesses. Combine with Name Tags You can find / generate accompanying name tag magnets using the post: Custom letters, numbers & name tags (OpenSCAD) , allowing you to generate: Planet and Sun name labels (3MF for English already included) Custom words Short descriptions Great for classroom labeling and interactive boards. Combine with Moon Phases For learning and visualizing Moon phases, the Sun and Earth magnets can be combined with magnets from the post: HueForge Moon Phases – Token Set + Container . Together, they form a modular Solar System + Moon phase learning system.   Combine with Box If you need storage for the magnets and/or name tags, you can generate a container using one of these posts: Round Gift / Storage Box (Customizable) Rectangle Gift / Storage Box (Customizable) Printing Tips Layer height: 0.2 mm Walls: 3+ Infill: 15–20% No supports needed Print face-down for best surface quality Insert magnet with a drop of superglue after printing. Included Separate 3MF for each planet and the Sun, including Rounded-edge geometry Editable magnet pocket Educational Use Great for: Learning planet names and order Classroom displays Interactive Solar System boards STEM kits If you like modular functional and STEM projects, follow for upcoming models.
