Tumbler orthographic drawing

I did this for a project in 1st year mechanical engineering in a 2D drafting course. It was made in AutoCAD and I based in on a similar drawing: [link]

The chair inside was based on [link]

It took way too long to complete (1258 objects, excluding the duplicate tumbler), but I did get a lot faster at AutoCAD. It also got posted on the wall outside my teacher's office.
