A 1:10 scale 3D-printed miniature model, based on the prototype of a common upper-limb traction device (also known as an upper-limb rehabilitation trainer) found in parks and residential communities.

Structural Replication:

• The black vertical post combined with a circular base faithfully replicates the support structure of the real device;

• The arched top bracket, circular decorative elements, orange non-slip handles, and the suspended black pull rope with handle all reproduce the core components of the actual equipment at a 1:1 scale;

• Clear color differentiation: the main body is black, the decorations are gray, and the handles are orange, accurately capturing the classic color scheme of outdoor fitness equipment.

  The vertical post was printed in three separate sections to avoid printing failures due to excessive height; the middle section can be added as needed, though it’s not strictly necessary, and the final result looks just like a real product.

  Assembly is straightforward. Below are the assembly steps:

  Prepare all printed parts
  First install the vertical post, connecting it via threaded joints, and then attach the handle linkage at the very top, securing it with the post nut.
  The handle is connected using screws and nuts. The four mounting positions follow the same procedure, but pay attention to the orientation: the braided pattern on the pull rope should face outward.
