These 25mm x 4mm ceramic magnets are the exact size used in COINFINITY stackers and bases, enabling secure, modular, magnetic stacking. Whether you're printing your own stackers or need spares for repairs or upgrades, these magnets are a perfect fit.
Use them to enhance stability between modules, align components on magnetic baseplates, or build your own custom stacking solutions. Each magnet is centered with a solid magnetic field and sized to drop cleanly into COINFINITY magnet wells. They get sealed inside the tubes, lids, bins and bases.
Features:
✅ 25mm diameter x 4mm thick (±0.1mm tolerance)
✅ Compatible with all COINFINITY stackers and bases
✅ Made from strong ceramic ferrite for durability
✅ Perfect for modular stacking and magnetic alignment
✅ Can also be used in DIY prints, crafts, and storage systems
Recommended Use:
Insert into stacker base cavities during printing pause. For best results, seat magnets flush and orient polarity for proper alignment. Works with all NFC-enabled stackers in the COINFINITY system.
Pack Options:
✅ 20-pack
✅ 40-pack
✅ 60-pack
Note:
These magnets are ceramic, not neodymium—designed for safe, stable stacking without excessive pull strength.
