This is a bookmark i made, remixing this model from printables: https://www.printables.com/model/569921-stop-sign/files

U can easily print at 0.20mm layer height. For the white "stop" text and border line, i simply set the slicer to stop at layer 9 (in my case) where i then swapped the filament to white and resumed the print. The picture of the model is the result. I hope you guys like this
