I could not find a good scale generator anywhere, for free, and the ones I could buy were not all that impressive. So I modeled up one based on the one I own.
I provided 3 scales; 1/16, 1/12, and 1/10th. I exploded the 1/10th so you could print using different colors.
You can use the power panel I made or you could make decals out of the pictures I posted and stick them on.
Or you could fake it, and download some other brand pictures and make decals.
UPDATE:
I made wall mount / rack and added it to the files.
Enjoy and Please post your makes.
