Simple to print, easy to assemble, lightweight yet sturdy, crafted with precision, designed for quick assembly—no supports needed during printing, no glue required for assembly! Plus, it’s highly durable, resistant to breakage, and boasts a smooth finish that makes it ideal for both indoor display and outdoor use.

Note: 1. If the parts are too tight to fit by hand, simply print the included tool hammer and gently tap the connectors into place.

        2. To prevent printing failures, we recommend applying a light coat of adhesive or using a release spray on the print bed—most issues stem from an overly smooth print surface.

Print without supports (though you can add a skirt to the base plate if it doesn’t adhere well), and assemble without glue or hardware—just apply firm pressure or give it a gentle tap with a small mallet if the pieces feel a bit snug. This is a truly convenient Chinese-style assembly model!

Catapult:

The catapult is a large-scale, human‑powered long‑range weapon that uses the principle of leverage to launch stone projectiles. Its emergence represented both technological advancement and the evolving needs of warfare. In Chinese chess, the black side’s “cannon” is written as “砲,” which originally referred to the catapult—and the character “fire” in its radical often denotes the ancient practice of “pao luo” (a form of torture involving burning). While the catapult was already in use during the Spring and Autumn period, it became a critical siege weapon in the Sui and Tang dynasties onward. By the Song Dynasty, however, it had seen even greater development, expanding beyond siege operations to become a vital tool for both offensive and defensive engagements in open-field battles. In ancient texts, terms like “throwing stones” and “flying stones” specifically refer to the catapult. Across the ancient world, the catapult was also a primary offensive weapon—used extensively by the Persians and the Greeks alike.
