Note: 1. If the part doesn’t snap into place when you press it down, simply use the tool hammer provided on the homepage—align it with the corresponding clip and gently tap it into position.

       2. To prevent print failures, it’s best to apply a thin layer of adhesive or a light mist of release agent to the print bed—most issues with failed prints stem from an overly smooth build plate.

The model requires no supports during printing (though if your base plate isn’t sufficiently adhesive, you can add a skirt around the perimeter). Assembly requires no glue or hardware—just apply firm pressure or gently tap with a small mallet if parts feel a bit tight. This is a remarkably convenient Chinese‑style assembly kit!

Si:

A mythical beast akin to ancient rhinoceroses, resembling a cow in appearance with dark, shaggy fur covering its entire body and a single horn adorning its head. The hide of the Si is exceptionally thick, making it ideal for crafting armor.
“The Si dwells east of Shun’s burial site, south of the Xiang River. It looks like a cow, with a dark, grayish hue and a single horn.” —From the Shanhai Jing, “South of the Inner Sea”

Assembly Guide:

We recommend using TPU or PLA Pro for the tracks—these materials offer superior flexibility. Of course, standard PLA works too; just be sure to stretch the track slightly before inserting it into the wheels, applying gentle pressure over time rather than forcing it flat all at once.
