As many, if not most, Monkey bike owners tend to upgrade their rear luggage rack to larger and sturdier one, they also lose the standard license plate mount. I wanted to create a slick mount for the plate and figured 3D-printing one with flexible and temperature resistant TPU plastic would work the best.
I designed the mount to have small lip above the plate to mount a tail light. The model was made in Solidworks and printed with Ender 3 Pro printer. As I saw there was some demand for these mounts, I posted a listing and sold couple of them as a kit with all the mounting hardware. (I still sell them, printed on demand!)
