17th Century Warship Paper Model

This papercraft is a free sample from a company that sells DIY 1:600 scale cardstock models of ships. Their products are intended for use in miniature wargaming. The sample model is of a specific historic ship: the Brederode, a 17th century Dutch warship. Building a ship of such a small scale takes patience, especially when putting together the masts and rigging which are made out of wire and thread respectively. The printable PDF template for the ship may be downloaded here.

Ten figures in all, the collection includes characters not typically seen in papercraft form, such as Draco Malfoy, Minerva McGonagall and Sirius Black. The PDF template for each character may be downloaded from Dias' website located here. Assembly instructions are also available.

ZZ Top Eliminator Coupe Papercraft

In the mid 1980's, the rock group ZZ Top took MTV by storm with a series of music videos. The videos all feature a distinctive red hot rod known as the "Eliminator coupe". The car currently resides in the Rock and Roll Hall of Fame Museum in Cleveland, Ohio. This papercraft likeness of the coupe was created by Patrick Pasques. The papercraft template for the car may be downloaded from his website located here. In case you were wondering, the coupe is a modified 1933 Ford.

Mini ThunderCats Papercraft

The thing I like best about this collection of mini ThunderCats papercraft is the model of the ThunderCats' headquarters, the Cat's Lair. Most fittingly, the Cat's Lair is in the form of a panther sphinx. Included in the collection are seven of the ThunderCats team (including Snarf!). These paper toys are by designer Gus Santome. The templates of all the figures pictured come in a single PDF which may be downloaded here. In the television show, the Cat's Lair was designed by the character Tygra, who, in addition to being a warrior, is also an architect. Who knew?
