I agree that if i was only doing one or two then the veneer approach would be easier. But I think i had to make around 45-50 of them so the jig is faster in the long run.
I approach most of my layouts the same when it comes to jigs. In this case a single opener is made with the fronts and the backs on top of each other as well as a profile cutline of the object to make the jig.
Make sure you think about which way you are going to flip them when you go to engrave the back. in my case i flipped them vertically.
I first import the file and them duplicate the openers to fill the space. Since i am using cardboard as a jig I leave some extra space between the objects.
Then just put in some cardboard and tape it down. After you cut the cardboard just remove the blanks and put in you openers. Just turn on the cut layer and turn on the front layer and engrave. Then flip all the openers, making sure to flip the right direction for your file. Turn off the fronts and turn on the backs and engrave the back sides.
The good part about doing it this way is you can easily adjust how many you are going to engrave. So if the last run has only two openers just delete the rest and engrave. I also make sure to undo back to the starting point if i delete any. That way the file is still setup for all of them next time i open the file.
The down size to this is the template has to be cut each time you power up the machine. But it only take it a few seconds to cut a new one.
The use of a snapmark template would make the template reusable and i will probably make one if i had another order of openers.
@evansd2 I’m not sure what the source of the bottle openers was because they were supplied by the client. But i can ask and let you know.
