prusaprinters

DescriptionOpenSCAD model to generate your own small (or large) key hanger in form of a German style license plate. Comes with a lot of customizable parameters to make it your own. Obviously, you'll need OpenSCAD software from https://www.openscad.org/ to generate the STL file.FontThe Font file (zip) can to be downloaded from the Internet or from the files section https://www.dafont.com/de/fe-font.font Just extract it next to .scad File.It's a variant of FE-Schrift, the official license plate font in Germany and other countries designed to be forgery-proofhttps://en.wikipedia.org/wiki/FE-Schrift MulticolorThe multicoloring is achieved with changing filament at layer-pauses. Please refer to the Prusa Slicer screenshot and https://help.prusa3d.com/article/color-change_1687BTW. My blue is a bit pale, but I didn't have any better filament on hand :-) CustomizationAll settings are in the beginning of the code and grouped. Use hole = false to disable the hole. To generate an STL File you need to render the model in OpenSCAD (F6) and export it as STL (STL button)PrintingApart from setting up pauses for color changes I recommend lowering the speed to 20mm/sBrim might help, although I didn't need it. I used ironing for smoother surface finish.If your frame and letters are very small I'd recommend increasing the usual printing temperature to let them bond better and if you have sever stringing maybe Z-hop will help. Some experimentation might be required for “top-notch” results.In my example 40x8 mm the print took 10 minutes Post-PrintSome cleanup might be required. Best done with scalpel/x-acto knife.If you're happy with your result post a make. I'll be glad to know your license plate number :-P
