gap is 80% of circle diameter
1. 10mm model is "8mm"
(last modified 2021.2.26 10:17 KST - first upload model have a 7.2mm gap, so too tight.
sorry for early downloader)
2. 9mm model is "7.2mm"

Once organized, I plan to re-post the fusion360 parametric model later in another post, which in my case will include information on how to print and use the label in the end. Please look forward to it and use it well.
