This is a model of an AK47, built to be printed on a 120mmx120mm print bed. It can be easily resized, but the 5mm hole on the end should be resized as well, to keep it constantly at 5mm. The hole is to feed through a carabiner or key ring. You will notice that there are two different files to when downloaded. The file labelled 'AK47 Key Tag' is the variant with a hole in the stock. If you just want to use it as a model, use the 'AK47 Model' file.
