Reconstructing an Eagle with Over 650 Metal Parts: BLDB Launches LED-Equipped 'Steampunk Eagle' in Japan

Precision metal model brand 'BLDB (Building Block)' is launching the 3D metal model 'Steampunk Eagle' in Japan, starting July 15, 2026. This product allows users to assemble the figure of an eagle with outstretched wings using over 650 metal parts.

This kit is an adult-oriented metal assembly model that uses gears, metal plates, and pipe-like components layered together to create a three-dimensional representation of the eagle's sharp contours and the dynamic sense of flight.

The finished size is approximately 30×40×20cm. Designed to offer different visual expressions from various angles, it features large outstretched wings, forward-reaching talons, and a multi-layered body structure. Additionally, the model includes display LED lighting inside the body. When illuminated, light emerges from the gaps between metal parts, creating a three-dimensional effect and shadows distinct from daytime viewing.

The product will be sold through the official BLDB online store. During the summer bonus sale period, customers can enter the coupon code 'SUMMER20' to purchase eligible items at a 20% discount.

Not just for display—building it yourself is part of the experience

The enjoyment of model kits isn't limited to admiring the finished product.

Opening the box, checking the parts, and gradually assembling them according to the instructions—watching flat metal pieces transform into a three-dimensional form—is a unique pleasure offered by assembly metal models.

The Steampunk Eagle consists of approximately 650 metal parts.

Wings spreading to the left and right, armor forming the chest, head contours, sharply curved beak, and talons extending forward as if grasping prey. By sequentially layering these fine components, the eagle's powerful silhouette gradually emerges.

The assembly process involves more than simply inserting parts; many steps require checking left-right orientation and part positioning. The estimated time to completion is about 3–5 hours.

While assembly time varies by individual, the design emphasizes enjoying the process—slowly building while confirming part shapes and structures—rather than rushing to finish.

Merging organic curves with industrial structure

The eagle, the model's motif, is a bird easily recognizable from a distance due to its large wingspan, sharp gaze, and powerful talons.

In the Steampunk Eagle, the creature's organic silhouette is preserved while feathers and muscles are reimagined using multiple metal plates, gears, and pipe-like components.

The wing sections use overlapping parts of varying sizes and shapes to create depth, mimicking the layered appearance of feathers. The body features metal plates resembling armor, finished so that mechanical structures are partially visible from within.

Rather than completely covering every detail, intentional gaps between parts create the impression that other mechanisms exist inside.

The combination of the hard, metallic texture typical of metal models and the organic form of a bird with outstretched wings is a defining feature of this product.

The three-dimensional presence created by a 40cm wingspan

The finished dimensions are approximately 30cm in height, 40cm in width, and 20cm in depth.

From the front, the wings stretching widely to both sides are prominent. From an angle, the forward-leaning body and talons convey a sense of depth, as if capturing the moment of flight.

Unlike small desk accessories, this model requires a certain amount of display space. However, when placed on a bookshelf, in a collection case, or in a model-building area, it stands out clearly and has a strong presence as a display piece.

The weight is approximately 800g. While it has a solid, heavy appearance due to the metal parts, it remains light enough to allow easy repositioning or relocation after completion.

Before purchasing, we recommend confirming that you can secure a display space of approximately 40cm in width and 20cm in depth.

LED lighting enhances the depth of the metal structure

The model includes LED components inside for display effects.

In bright environments, you can appreciate the color tones of the metal parts, the layering of plates, and the intricate gear-like structures. When the lights are dimmed and the LEDs are turned on, light emerges from the gaps between parts, making the contours of the wings and body stand out in three dimensions.

The LEDs are not intended as room lighting but as an effect to highlight the completed model's form.

During the day, enjoy the fine details of the precision metal model; at night, enjoy it as a display with light and shadow. The ability to enjoy different appearances depending on the time of day is one of the Steampunk Eagle's key features.

No glue required—assemble by combining metal parts

No adhesive is required for assembling this product.

By confirming the shape and attachment points of each part and assembling them accordingly, you can complete the three-dimensional eagle figure. Since there's no need to wait for glue to dry, the workflow remains uninterrupted, allowing you to proceed step by step.

However, because it involves over 650 small metal parts, it's important to ensure sufficient workspace before starting and to organize the parts by type.

Especially for parts that look similar on the left and right or for small fasteners, cross-checking with the instruction manual helps prevent assembly errors.

Rather than trying to complete everything at once, dividing the process into stages—such as wings, body, head, and legs—can reduce the burden during assembly.

Not for beginners, but for those who enjoy detailed work

Recommended for ages 16 and up.

While the estimated assembly time is about 3–5 hours, the model consists of over 650 parts, making it more suitable for intermediate to advanced users rather than a simple beginner's kit for those new to metal models.

Ideal for those who enjoy working with small components, those who enjoy the process of building structures while referring to instructions, and those seeking a model to display long-term.

It's also a great hobby gift for collectors of steampunk designs or bird-themed artworks.

Beyond gifting a finished product, it offers the recipient the enjoyment of the entire building experience. It can be recommended as a hobby gift for birthdays, anniversaries, or long holidays.

Support for missing or lost parts during assembly

In assembly kits with many parts, small components may be lost during work, or required parts may go missing.

BLDB accepts inquiries from purchasers regarding missing or lost parts.

After confirming the order number, purchaser's name, and photos or part information identifying the needed components, replacement parts will be shipped.

To prevent users from abandoning the assembly midway due to a single missing part, a support system is in place to assist throughout the completion process.
