Hello Printers, I'm thinking about entering the world of 3d printing---of course many, many questions. I won't ask about any make in particle (i have read past inquiries about subject) but would like to know about size of the work bed and if a closed or open unit would be better. This will be a hobby for myself and grandchildren nothing more. I am thinking of a printer which isn't basic nor top end but something that will allow some growth in hobby (not looking to print with metals or any special materials). I would like to print barrels, boxes, light poles, etc.---also vehicles like the jeeps (gunnerjohn) loads to fit on flatcars. Does printer have to be operated in a heated area or will an unheated garage work as you can see many, many questions. Also, will a need a computer to print items? Here's one question for now---if you find something on Tinkercad that is in ho scale how do you size for "o" scale in order to print. Finally, when I say "o" scale, what is the actual size 1:48? -----as always thanks for all your information and I'm sure will be back here with more questions Greg
