After being asked 6 times in one day if I was going to print out a gun I thought I needed a simple concise sign. Maybe others will need it too.
I really don't think guns are baaaad (m'kay). I worked in the firearms industry as an R&D designer for quite a few years and went through the long process leading to manned firings on new weapons. The idea that some idiot will now think its safe to print something off using any machine using any material with any ammunition type because they saw it on youtube really scares. Don't be an idiot please, there is a reason you make guns in a gun factory, not your kitchen.
Print it text side down for a nice crisp surface.
- Update 27 May. I used netfabb to repair the STL, some people had reported issues with using the file in Slic3r.
