This 3D world map has a size of 1.5m (width) by 0.75m (height), but can be scaled to fit your needs. It is split up into 27 seperate pieces to make it printable on machines with a smaller build volume. You need to be able to print at least 187.5 x 187.5 x 6mm if you are not scaling up or down. Countries have a height of 6mm and are surrounded by borders which are 1mm tall. Oceans aren't printed.

This world map can be printed in multiple colours on a regular (non-multicolour) printer. The part seen on the last picture was created with a stock Ender 3 Pro! Detailed files on how to achieve this are included in the ZIP.

SETTINGS
I recommend printing in PLA, because it's the easiest to print with. However, any material you like should work fine. This model doesn't require specific settings. You've probably printed with PLA before, use those settings that worked for your 3D printer. If you're having trouble with the first layer, try lowering your initial speed or change your Z offset.
