This is my design for a carryable stealthboy replica.

All you need is one of the new LC2 M16 vietnam mag pouches, wich you can get everywhere for a few bucks. I don´t know if the old ones have the same dimensions, but they should work too.
I got mine from MilTec.

I included a manual in the download, so you can start right away.
Some cutting and glueing skills are needed, but it´s some easy stuff you need to do.

The switches are moveable, but i recommend to let them remain static and glue them in.

Everything is made to print without any supports, but that deppends on your printer.

The TopCover and Frame are printed at 0,15mm, the other parts are all printed in 0,1mm layer height.
