Insurance Plate Holder Adapter 150mm

A simple design for a license plate holder or adapter for attaching an insurance plate to a larger license plate holder. The hole spacing for the insurance plate is variable from 23-33mm (not yet visible in the photo, this is a test print), the hole spacing for attachment to the original holder is 150mm. Originally intended for a Niu M1 Pro/Sport, unfortunately, the license plate rubs against the inner fender/"mudguard", which is why I chose a different approach for the actual use case. However, due to the 150mm hole spacing, it can certainly be used on other vehicles :)

To attach this holder to the original holder, I used M5 screws and nuts.
