Ending the Wild West of Smart Spools
An open-source initiative by Prusa Research creating a single smart spool standard that works across all brands and ecosystems. This allows printers and users to read and write data directly on any spool, making 3D printing more reliable and intuitive for everyone.
3D printers have become incredibly user-friendly, but interaction with filament is still a very manual process. To improve the user experience and streamline the workflow, we need smart spools.
A smart spool carries all the important information about the material and its workflow, unlocking key features:
Instantly identifies the material type and color, significantly reducing user error and leading to a simpler, more reliable workflow.
Real-time data tracking, such as the amount of remaining filament, so you always know the exact status of your material.
Enables effortless inventory management and full traceability by allowing you to log custom data.
Some smart spools already exist, but they lack the core principles of universality and interoperability. It's like every brand suddenly decided to use a different filament diameter.
Smart spools are often locked to their specific hardware and filament. This makes them unusable with any third-party machines, forcing users into a closed ecosystem.
Many smart spools just refer to an online database, forcing you to rely on the manufacturer's cloud service. No internet? Your "smart" spool becomes dumb.
Current Smart Spools offer little to zero reusability. This read-only design prevents any updates to live data, and once the filament is depleted, you have no choice but to throw the 'smart' spool away.

: Tools like Jacare act as a desktop library manager, wrapping the CrocDB API for a more traditional software experience.

Built for the murky depths of high-throughput systems where latency is the predator and downtime is the prey, CrocDB is the rugged, durable solution for developers who are tired of abstractions that leak.
Unlike traditional databases that primarily rely on disk I/O, CrocDB keeps the entire dataset in memory for reads and writes. However, it differentiates itself from pure caches (like Memcached) by offering configurable persistence mechanisms, making it a durable in-memory database . : Allows you to find specific retro game
func main() db, err := croc.Open(croc.Options Path: "/data/croc", FSyncMode: croc.Periodic, ) if err != nil log.Fatal(err)
The era of fragile, decorative databases is over. You need a system that has survived for millions of years. You need something that bites back. Unlike traditional databases that primarily rely on disk
was a centralized, open-source database and community-driven search index built to simplify access to retro gaming ROM links by unifying disparate, trusted internet repositories into a single searchable interface. Operable via its official domain crocdb.net , the platform operated strictly as a web aggregator and metadata provider. It explicitly chose not to host copyrighted binaries, games, or console firmware on its local servers. Instead, it relied on a robust Public API, native emulator integrations, and community contributions to build structured, highly queryable directories for digital preservation enthusiasts.
The WAL and snapshot files are stored in a specified directory. The WAL file is segmented (e.g., wal.0001 , wal.0002 ) to prevent unbounded growth. When a segment reaches a size threshold (e.g., 32 MB), CrocDB rotates it. An optional background goroutine compacts old WAL segments after a successful snapshot.
Instantly read or write in any orientation. This eliminates the need to rotate the spool to find the "correct" position.
Stick a blank tag on any filament spool you own, flash it using your printer or a phone app, and simply re-use it once the spool is empty.
A single tag works even for 2kg spools, ensuring live data is always perfectly in sync. Two-tag designs cannot guarantee this.
A 3D printer or any compatible device instantly reads all data the moment the spool is loaded.
