drawing in autocad that is needed for 3d modeling/printing

This drawing is for a tool used to undo a lid, i will have a separate tee piece with a diagonal end that sets into a diagonal shape in the center of the disks. ( to 4 different disks). The tee piece is inserted into either key 1, 2 or 3 and 4 and it is used to undo or tighten the lid. -PLEASE READ THIS DESCRIPTION CAREFULLY- I have already had a friend draw up the designs in auto cad i just want the drawings adjusted slightly, but i also need the tee piece drawn up on auto cad, and then all 4 disks and the tee piece 3d modeled so they can be printed out on 3d printer.(total of 6 parts) - I will need to work with you on design and give you measurements as they need to be exact. - I will also need to make sure they will work, this will mean aligning the drawings to the lids to make sure they line up and the shapes fit over each lid shape with approx 1mm around shape for ease of lifting the disk (4 separate drawings of 8 shapes) from the lids.(eight different in total) - This process will involve me printing your drawings on tracing paper and even possibly cutting each shape out . - You will need to be patient and provide me with an accurate scale so i can print off.
