Add-ons
Add-ons are ready-made parts you can attach to any face of your model — wheels to roll, plus arms and legs to pose. You add them in Assembly mode, and they travel with your model all the way to export.
Adding an Add-on
- Enter Assembly mode and pick the add-on you want from the toolbar.
- Click a face of the body to anchor it (a hint like "Click a face to anchor…" appears).
- Select the add-on again to fine-tune it — most can be moved, rotated, recolored, or removed.
Wheel
A rolling wheel you can place on as many faces as you like — multiple wheels per model are allowed.
- Tread: Street (smooth) or Off-road (chunky).
- Pull-back motor (Spring): turn it on to build a wind-up car. With the spring set to Assembled, the spring and cap print as separate parts that snap together by hand. Wind the wheel backward, let go, and it rolls forward. Available for L and M wheel sizes.
Robot Arm
A poseable arm that attaches to a face.
- Mount: Part of body (welded into the model and printed as one piece) or Separate part (prints on its own and snaps in).
- Attach shape: Ball (free swivel) or Square (keyed, holds its orientation).
- Slit direction: auto, or set it manually so the snap-fit slit points where you want.
- Use Move and Rotate to pose it.
Robot Leg
The same idea as the arm, shaped as a leg with a foot.
- Variant: Sneaker or Boot.
- Mount: Part of body / Separate part. Attach: Ball / Square. Use Move and Rotate to pose.
Tips
- Part of body add-ons need no assembly but print attached; Separate part add-ons print flat (often stronger and easier to support) and snap on after printing.
- If Separate part is greyed out, a neighbouring joint or mount is in the way — move it aside first.
- Wheels and detached arms/legs export as their own pieces; integrated arms/legs are baked into the body mesh.
