did a little digging and it seems that its not as easy. It looks like its only for the OP9 silencer and it cost money, around 10 dollars to support the dev of. That’s great, but I would probably open fusion or your cad of choice and engrave it there like you were saying. sorry for the misinfo

I haven’t attempted this yet but there is also https://www.openpewproject.org/ which has a customizer tab where you can put in all the needed info and upload your can and it will emboss it in a downloadable stl. Seems pretty cool regardless
