Tweakable Lego brick compatible model of the plate. Edit the model to tweak the number of pegs on top and bottom. The plate is sized to the number of pegs on the bottom. You can tweak the number of top pegs to non-standard dimensions, e.g. 4 pegs on top of a 3x3 platform.Lego bricks are manufactured to very tight tolerance, so make sure to calibrate the model carefully when printing, or bricks may not interlock properly.
