DND Simple modular map

I know there are quite a few designs out there to made modular DND maps, however, I really like this model that I have made just because it is so simple. It only requires three different parts and is fast and easy to print. If you would like to make more complex settings for your campaign you can also print various furniture pieces to add to your modular map. Make sure they are scales to a 28mm mini.
Below is my suggested number of parts to print per "set". I think it's a good ratio of floor:pegs:walls. However, feel free to print as many of each part as you want.

I recommend making it so that you have a square number of floor pieces and enough pegs and wall parts to go around it
once and across it 4 times. This is just the amount I deem to be about right, not for any particular reason.

You can use these equations to determine how many walls and pegs you might want for how many floor parts you want:

pegs = 8(sqrt(floorParts) - 1) + 4

walls = 8 * sqrt(floorParts)

For example for 10
