Easy to assemble, quick to deploy, highly reliable—and virtually indestructible!

Note: 1. If the piece refuses to move when you press it down, simply use the tool hammer provided on the homepage, align it with the locking tab, and gently tap it into place.

        2. To prevent print failures, we recommend applying a light coat of adhesive or a thin mist of release agent to the print bed—after all, the most common cause of failed prints is an overly smooth build plate!

This model requires no supports during printing (though if your base plate isn’t adhesive, you can add a skirt to ensure better adhesion), and assembly doesn’t call for glue or hardware—just apply firm pressure or give it a gentle tap with a small mallet if it feels a bit tight. It’s an incredibly convenient, authentically Chinese-style assembly kit!

The Gate‑Sealing Blade Cart:

This robust two‑wheeled vehicle was meticulously crafted to match the width of a city gate almost exactly. When a fortress gate was breached, the Gate‑Sealing Blade Cart served as a critical defensive tool, used to block the gap. By pushing the cart up against the gateway, defenders could both inflict casualties on attackers and effectively shield themselves from enemy arrows and projectiles. This made it exceedingly difficult for enemies to scale the walls, creating a mobile barrier that could be deployed swiftly and efficiently.
The “Mozi” records the strategic role of the Gate‑Sealing Blade Cart. In protracted sieges where securing the city gates was a constant challenge, this versatile weapon proved invaluable as a last‑minute defense mechanism.
