Everyone has it's own start with 3D printing. Mine was getting spare parts for a 40 years old car. I have started with a delta printer - Anycubic Kossel that needed a lot of upgrades. At that time, it was not possible to find a good source of upgrades, guides, manuals, so I created a Kossel wiki: https://www.lpomykal.cz As years passed, I have tried multiple 3D printers, but I still loved the delta design. So I created a large 3D delta printer as my bachelor's thesis at robotics. This is the outcome: https://www.youtube.com/watch?v=gyBQWvSRveA
