    • NFC Tags = 1 per stacker/bin
    • Rubber Feet = 4-6 per base

Base Components – Magnets

Magnets are optional for all models, but they add serious functionality. They enable vertical stacking with a secure and satisfying “snap” and increase stability. We recommend trying them out!

Printing With Magnets

Normally, printing with embedded magnets requires a stainless steel nozzle to avoid magnets pulling up and damaging the print head. But…

✅ Coinfinity stackers DON’T require a stainless nozzle!
The ceramic magnets are strong enough to stick to your metal build plate and stay put during printing — even with a hardened steel nozzle!

See the Magnets Guide for full details on magnet installation and safety.
