Quote - I try to match this in Blender, but up to now no success to extrude like the holder. I will announce results if I find the solution.

Zandar, I'm not sure which part you are trying to match, but the extrusions here are a little complex to describe, which is why I didn't get into detail about how to do them.  I"m not suggesting the technique or tools to do them are necessarily specific to 3dsmax, but it does impliment some tools in Max that I would not know what the equivalent would be in other applications.

In the most general of terms, you would begin by selecting the faces you wish to extrude, then make an extrusion from the normals with rotation along both the X AND Z axis.  I have these particular extrusions twisting exactly -15.4 degrees along the X axis, and -22.34 degrees along the Z axis.  The ending orientation of the extrusion is 40.7 degrees perpedicular to the original face(s) location.  If reading this sounds completely alien, don't worry; typing it felt that way too. ;)

I hope this helps in some small way, but in reality, the best thing to do is not worry about matching my results for this object; this isn't something that has a right or wrong design (aside from the fact it must hold paper towels).  You can take the tools you have, and use them to come up with your own original design, and that's the fun part!
