4 inch thick! Wow. I'm in the market for a 3d printer now, too cool not to have. Dont mind building one if someone has had good experience with a kit or used/ stand alone. Limited $300 budget.
The one I got for Christmas is $250 on Amazon. It was as low as $210 during the holidays. I'm doing a test print right now (2nd attempt) and so far it is looking really good. It's a Creality Ender 3 Pro.
