F-14 Jet

this file can be found on many sites, I enjoy this model because is it a good test for your printers calibration. as the jets wings can move (and certain structures snap away) this requires extremly fine detail, and any shaking or sloppy movements from the printer can result in a bad print. This model should be a good indicator of any issues. and if all goes well, you will have a very fun desk toy!
