How to Create Articulated (Flexi) Toys Without CAD Skills

Learn how to turn static voxel models into snap-fit articulated toys using Cubie.

The Problem with Static Models

Printing a statue is fun once. Printing a toy that moves, wiggles, and poses is infinitely more engaging. Usually, creating "flexi" or articulated models requires advanced CAD engineering to design clearance and hinges.

Cubie automates this process. You design the shape; the software calculates the joints.

Step 1: Design Your Stance

Build your character as a single object in Sketch mode. Ensure there is solid connection where you want the joints to be (at least 2×2 voxels). For a snake or dragon, build a long, straight body as this allows for the most consistent movement range.

Step 2: Enter Assembly

Click Assembly in the header. Cubie automatically:

  1. Finds connected components → splits the model into parts.
  2. Detects contact surfaces → generates joints.

The model immediately becomes poseable — you can drag parts and pose them.

Step 3: Refine

Use Assembly mode tools as needed:

  • Split Part — detach unwanted voxels from a part (via context menu).
  • Merge Parts — merge parts back if the split didn't work well (via context menu).
  • Reposition Joint — move the joint along the contact plane.
  • Relief / Round — add surface detail.

Tip: Every connection is a snap-fit ball joint by default. Select a part to change its joint type — Joint (ball-and-socket), One-piece (prints already assembled, no snapping needed), Spring, or Tight (holds a fixed pose) — and to fine-tune the bearing diameter.

Step 4: Print and Assemble

Click Export in the header. Choose orientation in the preview and download the STL.

After printing, snap the joints together — push the balls into the sockets. You'll hear a characteristic click. Your toy is ready!
