Another newbie Question, What to print first

Hi all....

I too and very new to this 3d printing, my wife bought my a CTC printer for my birthday and have only got round to printing the stock files off the SD card.

Currently I have been reading around some of the forums and have heard that there some parts (may just be for the CTC but could be the same for others) that would be good to have pre-printed in case of failure.

I was wondering does any know what parts you would print?

Also would you recommend any parts/modification to help with keeping the printer working.

Thank you
Steve

Print a few things like the test pieces from thingiverse to know the limitations of what it can do. Then do some shapes to test those limits. Then do something fun. Something you can look at and say "that's cool". Then go practical. Have fun with it while it's still new.
