It's a two-metre version of my low-poly world map, and the biggest printing project I've done so far. It took me a couple of months and about 5kg of filament to print (including some failed prints).
It is quite easy to print. Just print each individual file (79 in total). Use the last picture, which shows how the parts come together, to glue it together.
If you are not allowed to use nails or screws in your home, you can also use special double-sided tape (as I have been doing for a year now).
The exact dimensions are: 2,11m width x 1,02m height
