The model is in Pepakura .pdo format, which allows for much easier assembly/fit instructions than traditional written form. The designed scale is 1:270, although it is easy to modify to suit you desired size. Please note that the quality of the texture will degrade if the size is too large. Included in the .zip file is a sample texture file, which can be used to create your own paint schema. Please see the Pepakua site linked below for instructions on modifying the textures in Pepakura.
The files are presented in a compressed form, using .zip compression routines. An appropriate unpacking utility will be required to access them. Some files inside of the package are in .pdf format and will require a viewer capable of opening and printing them in order for them to be used to their original intent. In order to modify the texture files, an image editor capable of editing .jpg files will be required. The main model file is supplied in .pdo format, which requires a working copy of the shareware software Pepakura Designer © 2013 Tama Software. The software is available at their site: http://www.tamasoft.co.jp/pepakura-en/ and is free to download and use. A licence key is not required in order to print or modify textures. Pages are laid out to support Letter format, of 8.5” x 11” (21.59 cm x 27.94 cm). While it is possible they may be printed on A4, some modification to the layout may be required. Note that to create the models to the stated scale, no resizing through printing should be done.
