Cute model don't you think? I'm not too sure though if this papercraft is from a game or anime. To download, just open the jpeg and save it on your computer. Don't forget to get the instructions. There are other downloads like mp3s and wallpapers. Enjoy!

This model was released last december and I finished building it only last week. To download, right click on Hazel A-I and click "save target as." After getting all the files, you'll notice that the pages are of different sizes. Here's what you have to do:
1-Open MS Paint and create a page with the size 3305 x 4675 (that's the size of sheets A,B,C and H).
2-Open any of the remaining parts(D,E,F,G & I) with MS paint and copy and paste the parts to the first page that you created.
3-Colors the parts according to the label. Dark Blue for the parts of E, yellow for F, etc.
Now you can print all the parts without problems. Click the link on the bottom of the parts for the instructions.

Warning: These ship models are not for the faint of heart! Due to the very small parts, some people might find these too difficult to build. You can get an Aircraft Carrier, two cruisers, a destroyer and a couple more plus a Chinese warship. All these models are of the same scale which is 1/700.

I'm not really into car models but this one caught my attention. My first and only built car papercraft from epson didn't turn out too well. You can get a handful of small F1 papercrafts and also lots of helmets. Most of the models have only one page of parts. You can also get a pit and a part of a racetrack.
