Spring Festival Holiday Notice

Dear Valued Customers,

Hello!

In accordance with the national Spring Festival holiday arrangements and based on our team’s actual situation, our holiday schedule is as follows:

The holiday period will be from February 13, 2026 to February 28, 2026.

During the holiday, you can place orders as usual. We will start processing and shipping orders from March 1, 2026, in the order they are received.

We sincerely apologize for any inconvenience caused during the holiday period and appreciate your kind understanding. If you have any questions during the holiday, please feel free to contact us by email at xixiranran1419@gmail.com

or tbstron3d@gmail.com, and we will reply as soon as possible.

Wishing you all the best in the New Year—may everything go smoothly and may you be happy every day!

TBStron3D Team

Since there are both new and old versions of the Kobra 3 machines on the market, we kindly ask customers to identify their machine version themselves.

The old version does not require the first product (Y-axis motor mount, $2), while the new version does need to purchase it separately. We will ship the order according to the items actually placed.

If you're unsure about your machine version, you can send us pictures of your machine, and we will help you confirm the model.

If you previously purchased the upgrade kit but your machine is the new version, feel free to contact us!

Product Features:

Y-Axis: Integrated metal mounting plate with a dual-rail design, replacing the original dual-shaft bearing transmission system.

The dual linear rail system provides greater stability, reduced operational resistance, and lower noise compared to the original design.

The linear rail model is MGN9H L315mm, and different brand options are available.

Drawback: This upgrade kit will reduce the Z-axis printing height by approximately 3mm. However, after upgrading the Z-axis linear rail kit in the future, the printing height will return to normal.

The functions of the Z-axis linear guide rail upgrade kit are:

To replace the 6 POM wheels on the Z-axis, preventing wheel wear and avoiding situations where some POM wheels spin idly, thereby improving the machine’s rigidity.

The printing area remains unaffected, and the reduced printing height caused by upgrading the Y-axis linear guide rail is restored to normal.

The linear rail model is MGN12C L320mm.
