About this 3D model
Some 3D-Printable stencil files for the "Human Only" sign from District 9. I used a metal 10x14 Inch sign from the hardware store. All of the stencil files were printed at 90% scale(I designed them a bit too big for my printer so if you have a printer larger than 220x220 these files should work just fine without rescaling). I also have an instructables on this (https://www.instructables.com/District-9-Sign/) that details all of the stencil work and how to do the paintjob.
