Fully Expandable DND Tile System (With Walls)

NOW COMPATABLE WITH THE A1 MINI (use the 4x4 print profile)

This is a Fully Expandable DND Tile System that just clicks into place, and has walls that just slot right into the tiles. the top surface of the squares are exactly 1"x1" which means you can have a standard medium size mini on the tiles with two walls directly next to them, this allows for 1 wide hallways and better utilization of the corners of rooms.

NOTE: on the negative connection for the tiles, there is a small strip that is printed connecting the two sides of the hole, this is to keep the sides from warping and can be either removed by hand or cut off.

You should remove these small tabs of plastic

the tiles are a little difficult to put together once you go above a 3x3 (24x24 squares) so you may cut one of the middle tabs off of the large tiles to make it easier to connect larger sections together
Cutting at the red line will help if you are having a hard time connecting large groups of tiles together

Thank you @PolyFrog_365505 on printables for the base of the connection system

edit: walls were having a hard time standing up especially on their own or when the supporting wall fell down so i remodeled the long walls to have a support structure and i would suggest printing these walls (2 long standalone walls are now added too)

The 2 different 1x1 tiles explained:

because of the way these tiles work, there are only two different ways to make a 1x1 shown below

they both have different pros and cons and so i decided to release both of them, i have named them 1x1 normal (the one on the left) and 1x1 offset (the one on the right).

with a perfect square of 1x1s with side lengths that are even, both can be used to make an exact copy of the respective tile (eg. a 2x2 of both 1x1 tiles, if rotated properly, are practically indistinguishable from a normal 4x4) however, when used in odd amounts, the 1x1 normal will keep all the tiles aligned whereas the 1x1 offset will offset the tiles connected to it by 1 as shown below.

TL;DR: the two tiles are basically the same if you use an even number of them, but are useful for different things if an odd number are used.
