Custom 3D Fridge Magnet Maker – Photo to 3D Print
Create custom 3D printed fridge magnets and locker badges from any graphic. Automatic 6x2mm or 8x3mm recessed magnet cavities and multicolor 3MF export.
Custom 3D Fridge Magnet Slicer
Upload photos, anime art, or logos. The tool cuts a clean 6.2mm x 2.2mm press-fit cavity on the back for standard neodymium disc magnets and generates multi-color front relief.

Why Native .3MF Instead of Standard .STL?
Standard STL files collapse all colors into one single monochrome mesh, forcing you to spend hours manually painting triangles in your slicer. Our generator exports an open-standard 3MF archive with individual color objects and stepped Z-coordinates, giving you instant zero-effort AMS assignment.
From Your Image to a 3MF Model
Adjust your model in the browser, inspect the preview, and check the exported geometry in your slicer before printing.
Upload Graphic or Photo
Upload transparent PNG or JPG artwork. Mascot silhouettes and bold graphics make eye-catching magnets.
Select Magnet Cavity Size
Choose standard 6x2mm or strong 8x3mm neodymium magnet pocket with built-in 0.2mm friction tolerance.
Download & 3D Print
Export the 3MF file. Open in Bambu Studio, assign your AMS spools, and press-fit your magnet post-print.
Image Processing and Model Export
Review the processing workflow and choose settings that match your artwork and printing requirements.
Engineered Press-Fit Magnet Cavity
Precision calibrated 6.2mm x 2.2mm or 8.2mm x 3.2mm cylindrical socket on the backplate holds magnets tightly without messy cyanoacrylate glue.
Encapsulated Magnet Pause Workflow
Enables slicer pause layer so magnets can be dropped inside mid-print, sealing them invisibly within solid plastic.
Lightweight Anti-Slide Geometry
Optimized infill density keeps overall magnet weight under 18 grams, preventing it from sliding down glossy stainless steel doors.
Bambu Lab AMS Multi-Material
Generates distinct Z-stepped mesh tiers for 2 to 4 filament colors with zero coplanar slicing errors.
Smooth Front Perimeter Chamfer
Bevels exterior edges so the magnet feels comfortable in hand and resists chipping during daily use.
Instant Local Conversion
Zero cloud wait times. All calculations and 3MF packaging run in your browser via WebGL.
Calibrated Production Parameters
Tested slicing recommendations for Bambu Lab X1C / P1S / A1, OrcaSlicer, and Prusa MMU3 systems.

How do I make a 3D printed fridge magnet with a recessed magnet cavity?
Upload your artwork to ImageTo3DLab’s Fridge Magnet Maker. Select your magnet size (typically 6x2mm neodymium). The tool builds a 3.2mm base with an exact 6.2x2.2mm rear cavity for press-fitting, extrudes the front graphic with 0.8mm multi-color relief, and exports a 3MF file configured for Bambu Lab AMS or OrcaSlicer.
Frequently Asked Questions
Do I need superglue to secure the magnet?
The cavity includes 0.2mm press-fit tolerance, so standard 6x2mm neodymium discs friction-lock firmly. If your printer over-extrudes slightly, a tiny dab of cyanoacrylate (superglue) guarantees permanent hold.
How do I trap the magnet inside the print completely?
In Bambu Studio, right-click the layer height slider at the top of the magnet cavity and select "Add Pause". When the printer pauses, drop the magnet into the pocket, then resume printing — the printer will seal right over it!
What magnets should I buy?
We recommend N52 grade 6mm x 2mm or 8mm x 3mm round neodymium disc magnets. They are inexpensive and provide strong magnetic pull through stainless steel refrigerator coatings.
Can I turn a picture or photo into a fridge magnet?
Yes. A photo to fridge magnet workflow works best with a high-contrast subject on a simple background, because the image is reduced to a limited palette of stepped color layers. Pet portraits, silhouettes and bold logos keep their edges; busy low-contrast snapshots tend to look muddy. Export the 3MF and assign one AMS slot per color in Bambu Studio.
How thick should a 3D printed fridge magnet be?
A 3.2mm backplate is a good default: it leaves a 1.0mm solid floor beneath a 2.2mm deep magnet cavity so the disc cannot punch through, while the front graphic sits 0.8mm–1.2mm above the surface. Thinner prints flex and feel flimsy; much thicker prints waste filament and add weight.
Do 3D printed fridge magnets stick to stainless steel?
Many stainless steel fridge doors are only weakly magnetic, so use N52 neodymium discs rather than cheap ferrite magnets and keep the print under about 18 grams. If the door is non-magnetic stainless, use an adhesive-backed metal disc or place the magnet on a magnetic board instead.
