You can download this model in four scales (1:40, 1:80, 1:160, 1:200), but I don't know if they are fully printable, nor which is the best way to print it. That's why I presented it in three split options: front and back; right and left; and top and...

Using the following options: Mounting hole spacing = 0 Top lower center font = knewave.dxf/write Center lower size = 70 Lower right font = Letters/Letters Number of letters = 5 Rim bottom size = 60 Font spacing upper = 10/center/Letters/write Top...

The smallest scale (1:500) is perhaps too small to be printed with FDM technology, but it may be printable in resin (SLA or DLP). The file's names explained: name_1_x.stl is 1 : x. So _1_500 is 1:500 or one in five hundred. <br><br> I spend part...
