Stickers for MTU??

Hey all. I noticed some of you were using "stickers" for your throttle unit (as well as on some of the other hardware). I was just wondering where you got them from or did you print them yourselves? If you printed them how did you do it (where did you get the specific decals and what material did you use to print them on??). For the MTU i think I would rather use stickers than the 3D raised text.

Any help would be greatly appreciated

Thanks
