About this 3D model

Bank card sized self-deception ruler Convenient to carry around, confident every day. In addition to length measurement, a diameter measurement function has been added. I only have a monochrome printer, I suggest using a dual color printing scale for better display results. Entertainment works, please do not use them as actual measurement tools.
