Star Wars X-34 Landspeeder Paper Model

One of the coolest things to be seen in the very first Star War movie was Luke Skywalker's hovering X-34 landspeeder. Sadly Luke had to sell the landspeeder in Mos Eisley to pay Han Solo for transport off the planet Tantooine. This paper model X-24 was created by Dave Winfield and may be downloaded here.

Free Disney Princess Paper Dolls

If  my daughter were still young enough, its highly likely these free Disney Princess paper dolls would be on our papercraft to-do list. Released through the Disney Family website, these paper dolls are about as "official Disney" as it gets. Currently available are Belle from Beauty and the Beast, Ariel from The Little Mermaid, Aurora from Sleeping Beauty, and Cinderella. In case you're wondering, the Ariel doll does have a mermaid body hidden beneath those clothes. ^^ All four of the paper dolls may be downloaded here.

S.H.I.E.L.D. Helicarrier 64 Paper Model

In  books by Marvel Comics, helicarriers are flying aircraft carriers used by the intelligence agency S.H.I.E.L.D. In the Marvel Cinematic Universe helicarriers have appeared in two Avengers movies, Captain America: The Winter Soldier, and also on the Agents of S.H.I.E.L.D. television show. Some argue that a helicarrier also appears in the final battle scene of the Deadpool movie, but that is an ongoing debate. ^^ Obviously a Marvel fan, Tekzo has created a 1:800 scale paper model of Helicarrier 64 which appears in Avengers: Age of Ultron. One thing that impresses me about the model is that it includes tiny aircraft to place on the helicarrier's deck! The PDF template for the model may be downloaded here. The PDF is zipped inside a .7z file which may be opened with the free program "7-Zip".
