Thanks again for the help all. Lots to learn here. Some of the replies make me want to shy away, while others clearly point out that a 3D printer would save me a lot of money. Some of these interior parts can reach ridiculous prices. If I even printed 10 interior parts in a year, the printer would be paid for and after that, its all money in the bank. So hmm... decisions. My only concern is that even a "larger" desktop printer, only prints parts up to 8" or 20cm.

As one member posted above. That would print me a lot of parts, but I'd also run into plenty of times where it wouldn't be big enough. For me to set a good minimum... I'd have to say that I'd need to be able to print up to 12 inches or 30.5 cm. 1 meter would be ideal lol. But a printer that would print nearly everything I'd need would probably be able to print parts that were up to 22". Just to be on the safe side.

And something tells me that the bigger you get, the more expensive the printer.
