Where Whiskers Meet Wrenches
Raccoon Engineering: Masters of Mischief
Around here, we believe every great 3D print starts with three things: clever design, countless hours of testing… and at least one raccoon insisting, “I know a shortcut.”
We create high-quality 3D printable models for Bambu Lab and Anycubic printers that are designed to print well, fit correctly, and solve real problems. From printer upgrades and accessories to clever tools and workshop gadgets, every design is tested, refined, and occasionally rescued from a raccoon who wandered off with the prototype.
But for the real fun, check out the “Chatter” link in the menu.
Suuuure… Just one more mod!Yeah OK
MakerOnline Fans Welcome
This website is growing daily. Check back often. Welcome to the internet’s most suspiciously comprehensive collection of resources for the Anycubic Kobra X and Kobra 4.
What started as a few raccoons digging through dumpsters for spare printer parts somehow turned into one of the largest collections of upgrades, modifications, troubleshooting guides, repair documentation, and technical resources available anywhere. We’re still not sure how that happened.
Whether you’re looking for premium printer upgrades, printable accessories, maintenance tips, or trying to figure out why your printer suddenly sounds like it’s trying out for a heavy metal band, you’ve come to the right place.
Here you’ll find:
- The best Kobra X and Kobra 4 modifications from across the community, along with exclusive Raccoon Engineering designs.
- Complete troubleshooting guides covering the most common (and not-so-common) printer problems.
- Detailed printhead servicing documentation that walks you through repairs step by step.
- High-quality videos from Brian Cabalic covering maintenance, upgrades, diagnostics, and complete tear-down procedures.
- Installation guides, hardware lists, wiring diagrams, engineering notes, and plenty of photos to make even complicated repairs approachable.
- Honest reviews, clever upgrades, and practical solutions that have been tested by us—and thoroughly inspected by our Quality Assurance Raccoons (they mostly look for snacks).
Our goal is simple: create a single destination where Kobra X and Kobra 4 owners can find everything they need without spending hours searching through forums, social media posts, and random videos.
Whether you’re a first-time owner printing your very first Benchy or an experienced maker tearing your printhead completely apart for an upgrade, we’ve built this site to help you keep your printer running at its best.
So grab your filament, and explore the growing collection of guides, upgrades, and resources that make Raccoon Engineering the home for Kobra X and Kobra 4 enthusiasts.
Happy printing… and if something goes missing, don’t blame the raccoons. They already have an alibi.
