Kraken Motors from Devil Design LDO-42STH60-3004AH (S37 and S55) Extreme Stepper MotorRound shafts offer added support at the end of the shaft, making them great for high torque applications, frequent direction changes, and setups where extra stability counts. Recommended for High Performance Builds: If youre working on a high torque or high precision setup, a round shaft motor can help maintain accuracy under more demanding conditions. Maintenance Tip: Locking compound on grub screws will help ensure these motors stay securely

Round shafts offer added support at the end of the shaft, making them great for high-torque applications, frequent direction changes, and setups where extra stability counts.

Recommended for High-Performance Builds: If you’re working on a high-torque or high-precision setup, a round shaft motor can help maintain accuracy under more demanding conditions.

Maintenance Tip: Locking compound on grub screws will help ensure these motors stay securely fastened, even with repeated directional changes.
Both motor types are excellent choices for 3D printers, depending on your specific project needs. The D-cut shaft is user-friendly and reliable in lighter applications, while the round shaft offers robust support for high-torque demands.

Key Features:

  • High Torque and Speed: Conquer challenging tasks with the Kraken Motors' impressive power output.
  • Precise Control: Achieve pinpoint accuracy in your movements for intricate and detailed work.
  • Smooth Operation: Minimize vibrations and ensure consistent performance for optimal results.
  • Durable Construction: Built to withstand the rigors of demanding applications, ensuring long-lasting reliability. Class H insulated (180C)
  • Temperature Monitoring: This motor has an internal ATC Semitec 104GT-2 thermistor to keep a close eye on those motor temperatures.
  • Versatile Applications: Perfect for robotics, CNC machines, 3D printers, and other projects requiring high-performance motion control.

The high temp Kraken is finally here. Designed by Omranello from Devil Designs, these motors were made for applications where high torque is needed. This motor has an internal ATC Semitec 104GT-2 thermistor to keep a close eye on those motor temperatures. Included is a 1 meter long wire for the motor and thermistor, the motor wires are terminated with a 4 pin JST-XH connector.

Pulleys are not included!

Understanding D-Cut vs. Round Shaft Stepper Motors

When selecting between D-cut and round shaft stepper motors, both have unique advantages, making each well-suited to specific 3D printer setups.

D-Cut Shaft Motors – Popular and Easy to Use

Alignment-Friendly: The D-cut makes it easy to align set screws, providing a simple and user-friendly setup process.
Best For Light and Moderate Use: These motors excel in lighter applications where high torque and rapid directional changes aren’t a primary need. Perfect for builds that require steady, low-torque motion.
Maintenance Tip: We recommend using a locking compound (like Vibratite 125) on grub screws for added reliability, especially when used in lower-vibration settings.
Round Shaft Motors – Optimal for Stability and Heavy Use

very ergonomic
Color: Deep Black, Color: Deep Black
I bought this as a replacement for one of those gaming chairs that kills your back with a little lumbar pillow and this one is muuuuch better. the back support is everything you’d need and got rid of my neck pain after long periods of sitting and the seat cushion is supportive but still comfortable. It’s the kind of chair that you don’t really think about much because it’s so natural to sit in that you forget it’s there. The armrests flipping is a really nice feature too. One star off only because the head rest is so far back that i can’t really rest my head on it and every part of the chair that’s cloth is made of the same mesh texture like the armrests and seat. but i have no other complaints this is a good chair

Comfortable Ergonomic Chair for Long Workdays
Color: Black, Color: Black
I’ve been using this chair for my home office, and it’s been a great addition to my workspace. The seat cushion is thick and comfortable, even after several hours of sitting, and the mesh back keeps good airflow throughout the day. I especially like the adjustable headrest, which provides extra neck support when leaning back during breaks. Assembly was straightforward, the chair feels sturdy, and the wheels roll smoothly on my floor. The all-black design also gives it a professional look that fits well in any office setup. Overall, it’s a comfortable and affordable ergonomic chair that offers excellent value for the price.

Sturdy but uncomfortable
Color: Black
The seat itself is sturdy and easy to put together, I’ve now had the product for 8 months and had no issues wear/tear despite nearly daily use, but… it’s not comfy, at all. The seat cushion has a texture to it that scrapes at my legs if I don’t have an extra pillow on it or am wearing shorts. Additionally, the seat pillow is just kind of hard. It doesn’t give very much at all, so if I sit on it for more than an hour or two at a time my butt starts to get really sore. It works as a budget option, but invest in a good seat pillow if you plan to sit in it for any length of time.

A chair that does the job
Color: Black, Color: Black
I’m really happy with this chair overall. I wanted something comfortable, sturdy, breathable, and spacious enough for long hours at my desk when I work from home, and this chair delivered. I’d easily give this chair five stars because it exceeded my expectations in comfort, quality, and overall value. Comfort and Support The mesh back keeps it cool and comfortable during extended use. One of my favorite features is the adjustable lumbar support. You can manually position it exactly where your lower back needs support, and it fits the curve of my back perfectly. It provides great support without feeling too firm or uncomfortable. Build Quality and Design The chair itself feels solid and well-built. It doesn’t creak or make noise when shifting around, which makes it feel stable and high-quality. The seat is roomy and comfortable, and the overall design looks clean and modern. Easy Assembly It also came with an instruction manual that was extremely simple to follow, and assembly was very easy. I was able to put the chair together by myself in about 20 minutes without any help. Armrest Functionality I also like the armrests. They aren’t adjustable by height, but they do flip all the way up, which is surprisingly convenient. You can easily slide the chair under a desk or use it as an armless chair when needed. Packaging and Presentation Another thing worth mentioning is the packaging. Everything arrived extremely well-packed. Every individual part of the chair was wrapped securely, including bubble wrap protection for the components. The hardware and accessories were neatly organized, and the chair even came with the necessary tools for assembly in case you don’t own a drill or tool set. The presentation and packaging were excellent and showed real attention to detail. Overall Impression Overall, this is a fantastic office chair for the price: comfortable, supportive, sturdy, easy to assemble, and packaged exceptionally well. I’d absolutely recommend it and would confidently give it a five-star rating.

Solid quality and comfortable
Color: Light Grey, Color: Light Grey
Wonderful quality chair, solid and sturdy, it was easy to put together, the directions were very clear and all the pieces fit together perfectly without issue. It is made of breathable material and I love that the arms flip up easily. You can raise it up or down and it has an adjustable headrest. It also has adjustable lumber support. It rolls easily and the color is the only reason I might return, I think I want a different one instead. The chair is comfortable for a petite person but equally comfortable for a tall person. We have both in our family and it is great for both. The armrests are comfortable and there is really nothing negative to say about this chair at all. Considering the quality, it is a great value for the money.
