SuperTack Double-Sided Cool Plate 256x268mm for Kobra 3 - style: 256x268 green cold plate
About this item
- 【Dual-Surface Energy-Saving Cold Printing】This 256X268MM build plate is specifically designed for Kobra 3 Combo/Kobra 3 V2 Combo 3D printers, ensuring a precise fit and seamless integration. As a double-sided, drop-in replacement, it supports energy-efficient cold printing with minimal bed heat, reducing power consumption and electricity costs. It outperforms traditional build plates by delivering faster printing speeds, less warping, and stronger adhesion without glue, making it reliable for daily 3D printing tasks.
- 【Glue-Free Strong Adhesion & Low-Temp Performance】 Engineered as a high-performance "Cool Plate," it features a high-adhesion coated surface with anti-warping texture. It delivers exceptional adhesion at lower bed temperatures (30-50°C for PLA, 65-75°C for PETG,80-100℃ for ABS), no glue or additional adhesion aids needed. This design reduces power consumption, prevents heat creep, and ensures stable printing results—perfect for both beginners and professionals, compatible with a wide range of filaments including PLA/PETG/ABS/TPU.
- 【Advanced 7-Layer Durable Construction】 Built for ultimate stability, this build plate features a robust 7-layer structure. At its core is an aerospace-grade spring steel, sandwiched between impact-resistant middle shields and reinforced bonding layers. The exterior nano-porous oleophobic coating delivers superior scratch, rust, and corrosion resistance for long-term durability.
- 【Effortless Demoulding & Damage-Free Removal】 Allow the build plate to cool fully to room temperature before taking off your prints. Thanks to the flexible design, you can gently bend the plate to pop off finished models quickly with no extra tools. If you need to use a scraper, always lift from the edges softly to prevent scratching the coating, especially on the glossy side, keeping your plate in perfect condition for long-term use. This package includes 2 scraper blades only—no handles or screws. For use, please 3D print your own handle and purchase standard 0.2-inch diameter screws separately.
- 【Simple Cleaning & Warm Reminding】 Please re-level the plate before you change to another side to print; Please clean the surface regularly with clean water and a soft cloth . Do NOT wash or clean the cold build plate with any strong chemical reagents or strong detergents Please confirm your 3D printer’s build plate size before ordering for perfect compatibility. Each spring steel plate undergoes strict quality inspection before shipment to ensure reliable performance. We also provide considerate after-sales support. Feel free to contact us anytime for questions or concerns, and we will offer prompt solutions for you.

FAQ
What types of products does Stemora offer?
Stemora offers supplies for science experiments, microscopy, biology learning, measurement, laboratory organization, electronics, robotics, coding education, 3D printing, maker projects, and classroom activities. Available products and specifications may change over time.
Are Stemora products suitable for children?
Recommended ages vary by product. Please review the product description, manufacturer guidance, included warnings, and required skill level before purchasing. Products containing small parts, tools, electrical components, glass, or chemicals may not be suitable for young children.
Is adult supervision required?
Adult supervision is recommended for children and students, especially when using electrical components, sharp tools, heated equipment, glassware, small parts, or experiment materials. Customers are responsible for following all product instructions and safety precautions.
Can these products be used at home and in classrooms?
Many products may be suitable for classrooms, home learning, science projects, maker spaces, and hobby activities. Suitability depends on the specific product, learning environment, user experience, and intended activity.
How can I check what is included with a product?
Please review the product title, description, specifications, images, package quantity, and included-components section before ordering. Items shown for demonstration or scale in product images may not always be included.
How do I know whether an electronic or robotics part is compatible?
Check the listed dimensions, voltage, connector type, board compatibility, operating requirements, and supported platforms. Compatibility is not guaranteed unless it is specifically stated on the product page. Contact us before ordering if you need clarification.
When will I receive tracking information?
Tracking information is generally provided within 3–5 business days after an order is confirmed. In some cases, processing may take approximately 7–8 business days. Delivery may require an additional 4–5 business days after tracking becomes available, depending on the carrier and destination.
Why did my order arrive in separate packages?
Products in the same order may be shipped from different fulfillment locations. As a result, items may arrive separately and have different tracking numbers. You will not be charged additional shipping fees solely because an order is divided into multiple packages.
Can I change or cancel my order?
Contact us as soon as possible at vaioamaonaoak@gmail.com. We will try to assist, but changes or cancellations cannot be guaranteed once an order has entered processing or has been shipped.
What should I do if an item arrives damaged, defective, or incorrect?
Contact us promptly at vaioamaonaoak@gmail.com with your order number, a description of the issue, and clear photographs of the item, packaging, and shipping label. Please retain the product and original packaging while we review your request. Eligibility and available resolutions are subject to our Return & Refund Policy.
