I have designed a 2-piece license plate frame for US plate sizes. Because the Bambu build sizes aren't big enought to fit a whole plate, this design does not connect at the top or bottom it goes from the screw holes on the top and bottom and wraps around the sides. I know different states have different positions for their renewal stickers, but my state is in the top right corner so
I tried to have as minimal overlap as possible so it wont get in the way. The frame is symmetrical so two identical pieces make up the whole frame. I use ABS for the filament to help with durability being out in the elements. I have not tested in in below freezing temperatures or in the summer heat but I will update when it does. ASA may also be a good option for filament.

If someone can share sizes of the plates from their country outside the US I can try to make a version for those as well.
