Go for it. 3d printing is a game changer. One of the benefits is if you screw up, break or loose a part there's no need to buy another kit or search for a replacement, just print another one. Also, as long as I have the file I can build the kit as many times as I like and have a stash of unbuilt kits without out having hundreds of kit boxes.
There is a learning curve but once you get the hang of it it's pretty cool. 3d printing still seams to be in it's infancy and can only get better and easier to use. I see the day when most households will have a 3d printer just like we have paper printers now.
Thanks!
