Nothing CMF Makertools Backplate

This is my Entry for the Nothing CMF MakerWorld contest. I thought about the platform here and what people always use. i actualy was reverse engineering the a1 mini and had to check the drafting angles, but did not have a good tool for this. so here is a backplate with some handy features. InstallationSwap the Backplate to this one, by removing the screws that connec them to the phone. then add the ruler arm with an M2,5 x 5mm screw to the back, to add the functionality. Features: Corner Radius Checking You can put stuff in the corner and check the corresponding line to see, what corner radius is on that object. Unfortunately, due to space reasons, the number is not ideally placed. so you have to read the value when the object is removed. Angle MeasurementYou can use the Back to measure Angles as well. For example to get the drafting angle of a housing, put the phone next to the object on the bottom side and rotate out the arm until it stops. then you can check the value on the other a
