I've tried a lot to make a 3D model of frustum of cone but have been unsuccessful, so if anyone knows how to create one, please let me know cause I am a total noob and have just started using Blender and StackExchange, so please help me out here. Thanks in advance. Even if anyone has a pre existing model of cone frustum please let me see it. Help of any type will be highly respected.

You can simply add a Cone primitive and adjust the radius of the top (Radius 2) and then adjust the length and or bottom radius as needed.

A huge thanks,@iKlsR. This works very well – Nib Apr 22 '14 at 9:14

Starting with a default primitive of a cone and a cube from the add object menu. Place the cube so that it covers the tip you want to cut away.

Add a Boolean Modifier to the cone and set Object to Cube and Operation to Difference. After the modifier is applied you can remove the cube:

Start with a Cylinder select the top face in Edit Mode and scale the tip S.

The problem with Boolean is that it likes to mess with (read: destroy) your topology. Knife Project might be cleaner. – wchargin Apr 21 '14 at 23:15
