Frequently Asked Questions
Products & Compatibility
What grading companies are CoinConnex cases compatible with?
CoinConnex cases are designed to fit standard graded coin slabs from NGC, PCGS, CAC, and ANACS. The interior spacing accommodates the standard slab dimensions used by all major grading services.
What material are your products made from?
StoneFyr products are 3D printed in PLA and PETG depending on the product. PETG is an engineering-grade thermoplastic that offers higher strength, better heat resistance, and greater chemical stability.
Can I get a custom color?
We offer products in our standard color lineup. For custom color requests, contact us — availability depends on filament stock and order size. Custom colors may require a longer lead time.
Are the cases stackable?
Yes. CoinConnex cases are designed to stack securely. The modular design means you can build your storage system incrementally as your collection grows.
What's the difference between CoinConnex and SlabGrid?
CoinConnex cases are enclosed storage cases with sliding lids, designed to protect slabs during storage and transport. SlabGrid trays are open display trays designed for presentation, organization, and easy access.
