I am trying to this for my project. Provide your files in the IGS format.
This is quite a basic model, so I do not understand why you do not model this yourself, it is your project, so why not produce the model with own hands????
You did not ask for advise......your statement "Give model of following diamension"
Not a very polite statement......
you can share your own model and ask the problem. you may have a problem but you should make an effort to learn the reason.
