Description
While Wham Bam Systems already provides some jigs on their support page, there is none for common 40 mm metal coin blanks - yet.
Notes
The design is not symmetric. Because of its odd length the feet needed to be moved on one side. You can still print two, but they'll only align on the jig if one of them gets rotated by 180 °.
Included in the ZIP archive is a eufyMake Studio file. I wanted to provide contours, but these didn't work properly in version 4.1.2 for me, so you have to get by with black circles (locked and marked to skip printing) to align your designs.
Printing
Print with your favorite material and settings. I'd suggest a layer height of 0.2 mm.
Support is needed on the build plate because of the jig's feet.
I do not include supports by default, because your slicer should be perfectly capable to generate them itself. Plus you can adjust them to what works best for your printer and material.
License remark
Me using a "non-commercial" license does not prohibit you from using these commercially to print on bottle openers. But please do not sell the jig or the file itself.
