This is a very simple license plate adapter that allows you to mount most US motorcycle license plates on bikes directly imported from Japan, like an MC22 CBR250RR, for example.
The model only comes with one side of the adapter. Please duplicate and mirror the model within a slicer to get the adapter plate for the right side as well. To mount the plate, please use 6 M6 machine screws and nuts. I used 6 M6x10 screws, which are a bit long, but they get the job done.
Use PETG or any other more heat-resistant materials for best results.
Despite its simple appearance, this model has quite a lot of rough edges. This is my first CAD design ever, and it may not fit your usage case at all (though it certainly fitted mine). Feel free to remix it!
