This is an open ended widget that you can use to attach a Moto tag to your design.

The STL file is generated from the attached SCAD file with openscad. I measured the tag with a micrometer and then adjusted some of the parameters after a couple of test runs. It is my first time using OpenSCAD so maybe not perfect, but seems to work. I had not used OpenSCAD before, so earlier versions of this file were based on code generated by Google's Gemini LLM. The SCAD files requires the BOSL2 library. Instructions for installing this with OpenSCAD are easily googled.

I tried to make a bevel out of the middle - it isn't quite what I was hoping for in terms of "snapping" a moto tag in place, but everything seems to hold fine. The material is pretty thin due the bevel so depending on your material, you may be able to see that the tag is in there, which I have classified as a feature, not a bug :)
