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

Loved it
Bought this for my 3 year old son and if it’s perfectly on his toddler, bed would definitely recommend. I love the fluffy and cooling effect. It gives is very soft. It feels amazing. Especially for a toddler very comfy.

Great pillow & Machine Washable
A little on the firm side at first, but it's getting softer with a little use.

Fluff this in the dryer and this is the perfect pillow!
I bought throw pillows from this same brand and was disappointed until I read a tip in the reviews to place them in the dryer on fluff for about 20 minutes. That did the trick and one saved me after a rotator cuff injury. I used it for months to prop my arm up and prevent pain in my shoulder. I loved it so much I decided to see if this brand made a pillow for sleeping and was excited to find they did! This one took two rounds in the dryer on fluff, but I couldn't believe how soft and fluffy it got. I have been getting the best sleep ever since. If you get this pillow, I highly suggest throwing it in the dryer. It makes a huge difference!

Comfortable
This is the fluffiest pillow I have ever bought. I bought it for my 5 year old. He is extremely happy with it and makes him feel like he finally has a big boy pillow that supports him when he sleeps. I might buy one for myself. Defiantly a good purchase.

Fabulous
This is a fabulous pillow. I love it. I recommended wholeheartedly. It is however, large larger than I was expecting. Fortunately, I had a large pillowcase that fits it.
