Create a Cube. 1: Select a face 2: Pick the Boundary selection tool 3: An edge loop is created 4: Copy 5: Paste 6: A square of the same size as the cube is created.

1: Select all edges (CTRL/Command + A) 2: Create a small bevel 3: The result.

1: Move the curve 2: Hide the cube 3: With CTRL/Command key pressed, move your manipulator to extract a ring of polygons

1: Pick an edge and select the Ring selection tool 2: Create a small Bevel of the current selection 3: Apply a Thickness 4: Pick an edge and select the Ring selection tool 5: Loop selection tool 6: Create a small Bevel of the current selection 7: The result

Unhide the Cube and select the previous object 1: Pick the Snap tool and click with Shift key pressed on the center of the selected object (green dot) 2: With Shift key still pressed, pick the center of the cube 3: Copy and paste the current object to create a copy, do a 90° rotation (Rotate with Shift key pressed)

Do a small scale on the vertical axis to avoid the overlap of the two rings (spike of the arrow)

1: With the Curve tool, create a kind of open knot, like a flat heart drawing 2: Press down CTRL/Command key 3: Move forward to generate a band of polygons

Clone the previous object in the edit menu

1: Select the 4 vertices of the strip (only one, not both) 2: Activate the soft selection 3: Pick the scale tool along the axis along the strip 4: Scale until your strip creates a kind of star. The clone generate the same result on the other strip automatically 5: Apply a thickness

1: Pick an edge and select the Ring selection tool 2: Loop selection tool 3: Create a small Bevel on the current selection 4: The result

Put the knot on the top of the previous strip and box.

1: Create a grid (7x2) 2: Pick a set of two contrary vertices and do a constraint scale along the axis 3: Move some vertices to raise the band

1: Apply a thickness and do a loop select of the contour of the object 2: Select the corner edges 3: Create a small Bevel of the current selection

Add your band to the previous modeled object. You can preview it with applying a level 3 smoothing (Page Up key three times.)

Your model is now finished. You can export it to any other 3D software to generate the render. Feel free to follow the other tutorial, with Carrara and this gift!
