For rooms.

Made on request, this is simply a big checkered block made for visually measuring
distances between objects.

This block is 10,000 meters long x 2,000 meters wide x 1,000 meters tall.

The squares on it are all 1,000 meters long x 1,000 meters high.

That's it. Just place one or more than one in your room and measure stuff.
The block's squares are numbered for faster measurement.

Enjoy!!! ^_^
