Have you seen how many parts there are? It would probably take most people with a normal day job a week to print all parts in the evenings and weekend. And that's if they do have a printer.

Add another 20 parts that you need to order from different place, make sure they meet the specifications, pay for shipping for a lot of different packages and that many things must be bought in bulk and not single pieces.

USD 200 is a bargain for this kit. Sure, you might be able to save a couple of dollars if you do the work yourself. But is that worth many hours of work, and the risk of ordering wrong stuff?
