The pegs on this board are compatible with standard LEGO bricks.
There are 25 x 25 pegs (200mm square).
I was amazed that it printed so well and worked the first time. Bricks stack on it perfectly-- not too loose or too tight.
The plate is completely flat on the bottom.

Notes:
LEGO compatible plate 200mm (~8inch) square, with a 2mm thick plate. I have also included a .8mm (or "Thin") version to print faster, with the idea that it gets glued to a table-- I expect the "Thin" version will be easy to break, unless you're going to support it. I only printed the original version and it works great (see image).
25 pegs in both directions. If there is enough interest, I might put in the effort to try it out as a customizer part, so you can set how many pegs you want in each direction.
More Settings Details:
I used the concentric infill pattern to keep the support uniform for all pegs, and it took my printer about 8 hours.
In case you are worried about printing size, I added a small version (4x4) for a quit-printing part that won't use up much filament. You can print this first and then scale as desired for a tighter or looser fit.
