My 13 year old son is asking for a 3d printer. I know less than nothing about them. After some google searches, I am leaning toward buying a Creality Ender 3 V2 for $200, but I would like to know if you recommend something different. Also, what else do I need to buy? I know I need filament but there seem to be different kinds of filament, where is a good place to start?
