Filament Spool Winder – Automatic Respooler

A fully assembled filament spool winder that recovers loose or scattered refill coils and transfers filament between spools.

Rescue Loose Refill Coils

When a Bambu or third-party refill coil springs open, collapses, or becomes loosely wound, the respooler helps transfer the filament onto a usable spool with less manual handling.

Transfer, Split, and Reorganize

Transfer filament from damaged, paper, or incompatible reels, divide bulk rolls into smaller spools, or rewind unevenly arranged filament to support smoother feeding.

This filament spool winder recovers refill coils that spring open, collapse, or become scattered before they can be loaded correctly. The automatic respooler can also transfer filament from damaged, paper, or incompatible reels, move a full roll between spools, divide bulk filament into smaller rolls, and reorganize uneven winding. Sensor-controlled start/stop, adjustable speed, and a belt-and-gear drive reduce manual monitoring and help maintain steadier winding. The fully assembled, 3D-printed ABS unit supports PLA, PETG, ABS, TPU, nylon, and similar 3D-printing filaments.

Automatic Filament Respooler Overview

Loose 3D printer filament spilling out from a spool after the filament has slipped off the reel.

Why It is Better than other Winder?

Ready instead of DIY: The fully assembled ABS-printed unit avoids printing parts, sourcing motors, and tuning a homemade winder.
Less manual monitoring: Sensor-controlled start and stop reduce hands-on operation compared with basic manual winders.
Steadier winding: The belt-and-gear drive and adjustable speed help maintain more consistent winding across different filament conditions.
Broader material handling: Adjustable speed supports common rigid and flexible 3D-printing filaments.

No. The current receiving-spool configuration is designed for 1 kg spools only, and a 3 kg version is not currently available.

Is the respooler available with different power supply versions ?

Yes. We automatically include the power supply version and plug type appropriate for the destination country or region, based on the shipping address. If you have a specific plug requirement, contact us before ordering.

Support FAQ

What Should I Buy from Call3D?

Call3D is particularly valuable when you are looking for:

Carefully selected third-party accessories, mods, and upgrades for Bambu Lab printers;
Compatibility-sensitive parts that require clearer model, version, or installation guidance;
Specialized solutions that may be difficult to identify on general marketplaces;
Newly released or locally unavailable Bambu Lab products;
Multiple accessories that can be combined into one order.

Every product we list is selected for a clear functional purpose, with compatibility, installation requirements, and known limitations reviewed before publication. Our goal is to help customers choose the right solution—not simply offer the largest possible catalog.

Why Call3D over a Marketplace?

General marketplaces may offer a large number of similar-looking products from different sellers, making it difficult to evaluate compatibility, product quality, and after-sales responsibility.

Call3D operates as a specialist curated store. We review a product’s purpose, compatibility, installation requirements, and available technical information before listing it. If customers need help before ordering or encounter a problem afterward, they can contact the same team that selected and documented the product.

We focus on long-term customer relationships, clear communication, and responsible after-sales support rather than a one-time transaction.

Call3D Store & Service Reviews

I’ve known Enderwick since 2014 and worked alongside him for many years. With over a decade in the industry, he and his team bring an extremely high level of expertise.He has built an enormous 3D printing community here in China and is always coming out with new solutions—each one never fails to impress me.

When EP invited me to Shenzhen back in 2019, I was absolutely blown away by the hardware innovation coming out of China. Just one year later, Bambu Lab burst onto the scene—and their solutions have grown right alongside Bambu, evolving from the very beginning to where they are today.

Bought a ventilation system but changed my mind last minute. I thought returns would be a huge hassle, but they told me there’s a return warehouse in Houston only about a 10-minute drive from where I live in Missouri City. Drove over and returned it super easily. Super convenient return process, great experience overall!

Found this shop on Reddit, chatted with a real person about the P2S filter I needed. Asked if they could ship to SG, they checked and made it happen! Super happy because this filter is basically impossible to find locally and always out of stock everywhere else. Fast, friendly, and solved my problem perfectly. Will buy again!

Fantastic. Well built. Does a great job. I hesitated to buy something I could theoretically build, but I'm glad I did. Well worth it.

Thanks for shop with us! It’s great to hear the winder produces a more even spool with less effort.

The winder works really well. I had a few questions during setup, and the seller provided clear, thorough instructions and was very patient throughout. That made the whole process much easier.

Thank you for the kind feedback! We’re happy the winder is working well and that our guidance made setup easier. Please feel free to reach out anytime.

Honestly, this is a no-brainer. It’s incredibly easy to use—just press one button and it does the job. Super useful, super simple, and seriously impressive. If you’ve ever had a spool collapse or the filament come loose, this thing can save the whole spool.

Thank you! We’re glad the one-button operation made respooling easy and helped save your loose filament. That’s exactly what this winder was designed to do.

This works extremely well. I previously bought an air purifier from this store and came back for the spool winder. It winds filament much more evenly than the DIY version I printed and other winders I’ve tried, and the best part is how hands-off it is. I’m planning to try the filament-splitting function in the next few days. Definitely recommended.

Thanks for coming back to shop with us! It’s great to hear the winder produces a more even spool with less effort. We hope the filament-splitting function works just as well for you.

This is the first time I’ve sat down and written a review this seriously. LTS DESIGN clearly knows mechanical engineering. The winder solves a relatively small filament-tangling problem, but the mechanism and design thinking behind it are genuinely clever.

There are two things that really make it worth buying. First, the support is incredibly responsive and answers questions almost immediately, so any issues during setup or use can be resolved quickly. Second, the machine runs very smoothly without jamming, includes overload protection, and handled a continuous one- to two-hour run without any problems.

I sincerely hope the seller keeps offering products and support this way. It makes the whole experience much more interesting and enjoyable.

Thank you for taking the time to write such a thoughtful review. We’ll share your comments with LTS DESIGN. We’re especially glad the smooth operation, overload protection, and responsive support stood out.
