Also, all the base components should have a page on the official wiki. I take it you've been exploring the API section, but you might have overlooked the Components one. In particular, this page on 3D Printer has a list of all its functions, as well as their short descriptions - check it out!
As for the components not present on the wiki (added by various addons) or just for the in-game quick reference, you could easily use @payonel's method, too.
Did it help?
Aww!.. It seems to be very good program, so it is only making worse the fact this link doesn't work for me - it seems that it was deleted from that website somehow, but I may be mistaken... If it is broken, could you please fix it? If it is not, I'm really asking for help with the issue. >.<
I simply *adore* 3D-printer since it's discovery only a few hours ago () - (freshly-baken Security Uranium Rod and Forcefield should go well together ^^), but making models with 'edit' just too slow and hard, as imagining all these coordinates at once is a challenge... Utility from F0x06 is much bet
