Everything else is just incremental part upgrade (brake change, lever change, dynamo change... etc) that can be done yourself easily.
I recommend to get any MK4 frame (avoid bent or rusted ones of course) and put quality parts yourself.

12 years can bring quite a bit of innovation. Back in 2003 dura-ace 7700 was the latest and greatest. MTB bikes had rim brake and 26 inch wheels.
Now we have wireless electric shifter, sub-600gr mainstream crankset, affordable carbon clincher rims, road hydraulic brake, 10-51T cassette etc...
I recently saw that nowadays a full carbon roadbike with Shimano Claris STI lever can cost less than $500. That's some serious innovation IMO.
About 3D printers, personally I own a Form 2 and Ultimaker 2+ but it seems both of them are already surpassed by new affordable ones.
