What It Is

BadCatBricks is a custom design and building-instruction website for LEGO enthusiasts. It offers step-by-step instructions for a variety of original models, complete parts lists, and BrickLink part lists to help users quickly source the required bricks. The site also showcases its LEGO model design and build for the USS Cleveland LCS-31, which is displayed at the Great Lakes Science Center in Cleveland, USA.

Core Capabilities

From an e-commerce perspective, it is not a third-party seller marketplace, but rather a niche shop focused mainly on self-operated digital content. Its products are primarily LEGO MOC design plans and instruction manuals, covering themes such as dragons, robots, aircraft, race cars, trucks, motorcycles, rovers, and Technic structures. The instructions emphasize ease of use: each step is individually numbered, no more than four parts are placed per step, and they include color images, arrows, notes, as well as guidance on Technic pin depth and axle length. For users, the BrickLink parts list is a key feature, reducing the friction between following the instructions and purchasing the required pieces.

Pricing and Fulfillment

The available content only shows a “Design Store” and “Free Designs,” without disclosing specific prices, payment methods, refund policies, or membership subscriptions. In terms of fulfillment, the site focuses on downloading building instructions and obtaining BrickLink lists, and does not state that it directly sells or ships physical LEGO parts. As a result, users will most likely need to purchase bricks themselves through channels such as BrickLink.

Pros and Cons

The advantages are its clear positioning, highly focused content, and user-friendly instruction details, making it suitable for builders who enjoy large models, minifigure-scale models, or Technic builds. The free designs also help new users try the service. The downsides are limited transparency around commercial information, with insufficient details on pricing, payment, localization support, and after-sales service. It also states that it is not affiliated with the official LEGO brand, so users should clearly understand that it is a third-party source of original designs.

Who It’s For

It is suitable for MOC builders who already have some LEGO experience and are willing to source parts themselves, as well as enthusiasts looking for unofficial themed models such as aircraft, vehicles, dragons, and robots. It may also suit organizations or individuals with exhibition needs or custom model requirements who want to submit a bespoke project request.

Access from China

The collected content does not provide information on access from China, a Chinese-language interface, RMB payments, or cross-border shipping. Its accessibility from China is therefore unknown.
