Simple to assemble, easy to build, material‑efficient, highly detailed, quick to put together, resistant to failure, tough enough not to break easily, requires no support structures during printing, and can be assembled without glue!

Note: 1. If the parts won’t snap into place by hand, simply print the included tool hammer and gently tap the clips 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 print surface.

Prints require no supports (though if your base plate isn’t adhesive, you can add a skirt around the edges for better adhesion), and assembly doesn’t call for glue or hardware—just apply firm pressure or give a gentle tap with a small mallet if parts feel a bit tight. This is a truly convenient Chinese‑style assembly model!

Tong Tong (tong tong)

A mythical beast resembling a wild boar, said to carry a precious pearl within its body. It dwells in the mountains and lets out a cry that sounds just like its own name—“Tong Tong.”
There is a creature whose form is like that of a pig but adorned with a pearl; it is called Tong Tong, and its cry itself is its name. —From the “East Mountain Classic” in the Shanhai Jing

Assembly Guide:

To install the roller, use a lighter or hairdryer to gently soften the frame before fitting it into place—and once assembled, carefully bend it back into shape.
