Match these heights in your slicer. Adaptive layers need a separate check.

Base colorUse a custom base color

The base counts toward your printer’s color limit. Assign filaments in your slicer.

Magnet placement

Coordinates start at the artwork’s bottom-left, in millimeters. Every separate piece needs a magnet.

Total thickness is calculated from the magnet, clearance and these layer counts.

Cavity fit and spacing

Adjust fit clearance

Extra diameter (mm)Added once across the full diameter, not on each side.Minimum extra depth (mm)The resulting depth is aligned to whole print layers.

Diameter allowance is added once across the full diameter. Layer alignment can add depth.

Minimum wall / spacing (mm)Material around cavities and between cavity edges.

Test the fit

The optional test has an open top so you can check magnet fit. It is not the enclosed final magnet.

Weight & holding strength

Mass assumes solid plastic. A pull-force rating is not a vertical holding measurement through plastic. Test on the intended surface through up to of plastic.

How to test holding strength

Remember my print settings

Artwork and holding measurements are not saved.

Before your first print

Measure your magnets and check the fit allowance.
Import the 3MF as one assembly and assign filaments.
Verify the insertion pause, then make a supervised test print.

Built from your artwork

The generator uses filled vector geometry and real solid operations. It preserves your silhouette and holes, with no automatic backing or bridges.

Artwork colors appear only in the top section. The lower section uses your selected base color.

Preparing artwork for a clean print

Supplies for your first magnet

Measure your magnets before generating cavities. Use filament and a printer you already have when they suit the job.

A few useful answers

Can I start with a PNG or JPG?

Yes. The local image tracer turns it into simplified color regions. Review the traced shapes and holes before using them. Logos and drawings usually need less cleanup than photos.

How are magnets enclosed?

The model has a bottom skin, open cavities during printing, and a roof above them. Pause after the cavity walls finish and before the first roof path. Insert the magnets below that plane, then resume. Verify this in your slicer.

Does a four-color printer need a fifth color for the base?
