Here's my 20 years of progress. From scratch built mechs from bits of styrene to fully digital and detailed 3D printed models. What a time to be alive.
I'm just waiting for the day 3D printers get so advanced we go to the store. Buy Hasbro brand filament. Buy an STL file from Hasbro. And then print our official Transformers, in the quality that comes out of the factories in Vietnam, but in our own home.
I have a list of all G1 characters that have been released in CHUG form. You can find it here. Please feel free to let me know if I got anything wrong so I can fix it.
