Put a Cap on It

You can easily create a cap for your bottle using a black cube and a bevel modifier to round off the cube's edges. In Object Mode, position the 3D cursor (Figure 2) over the bottle, and create a cube with Ctrl+A. Press S to scale the cube so that it fits nicely on the bottle.

Then create a new material and color it black. This time, choose the Principled BSDF option. Now switch to Properties | Modifier Properties and use Add Modifier | Bevel to create a bevel modifier and round off the cap's edges. Leave the Amount at the default value, and increase the number of Segments to 6. Now apply Object | Shade Smooth to complete your bottle cap.

Insert Tube

Finally, create the fine tube used to connect the atomizer (hidden by the cap) to the perfume in the bottle. Simply create a path in Object Mode with Ctrl+A and use Add | Curve | Path. Move or rotate the path with G and R until it is vertical. Then switch to Edit Mode and move the lowest control point slightly to the right to create a slight curve in the tube.

Once you are satisfied with the curve, add some volume to the path by selecting Properties | Object Data Properties | Geometry | Bevel | Round. Increase the Resolution parameter to 4. Finally, the tube needs to be transparent. You can use the same material as you used for the glass bottle. As a final step, position the tube in the center of the bottle with G.

All done! Figure 14 shows the completed perfume bottle.

Conclusions

The longer you work with Blender, the more intuitive the above steps will become. Considering everything possible with Blender, this perfume bottle tutorial is only a modest beginning. If you get stuck as you venture forth with Blender, don't hesitate to ask for help, perhaps on a Blender forum [2], or look for a Blender Meetup [3] where users get together in person and share their experiences and techniques. My final advice: Don't give up too quickly!
