Cuts nicely with 2mm endmill. I did the engraving of numbers etc. with 55degree V carving bit. This is quite large (about 16cm x 17cm) so you might want to scale it down a bit.Please note that this doesn't comply with parking disc standards in Europe so you could get a ticket if you use it.Icluded are Artcam 2008 files and a basic Dxf .cnc files were used to cut this with mach3 using 2mm endmill and 55 degree V-groove engraving bit.
