Hi can anyone help me how to model the attached shampoo bottle cap having push top
Think of it as a cylinder, hollowed out. (booleaned would work.) A notch is shaped or cut out of the back.
A flat disk is placed inside with the front having a hole in it.
Welcome!
Here is how to do it:
1-Start by doing an inset on the top of a cylinder.
2-Extrude the face inward.
3-duplicate the face with shift+d, scale it down a little and move it upward. This will be used for the middle part.
4-Extrude the new part to give it thickness and place it at the correct height.
5-Move the edges on the outer cylinder to create the curved notch.
6-Shade the model smooth. You can also activate auto-smooth and mark sharp to keep sharp edges flat shaded.
7-For better quality, add a bevel modifier. Don’t forget to check “harden normals” on it, or else the bevel’s curved shading will bleed on the straight faces around.
Alternatively, you could use a subdivision surface modifier instead of bevel and control the look of the model with edge loops and creases.
