This is everything you need to get started for creating your own pixel art creations!
I included a number of basic sizes that can be used by default, but I also included the step file of a single peg so you can make whatever size you want. I also included the step file for the pixel itself in case you need to change the tolerances for your printer.
I'd recommend starting with a 5x5 and a handful of pixels to test the tolerances. I've found how the pixels fit on their pegs really depends on the individual filament.
You'll need to clone the pixel inside your slicer for however many you need. It's worth noting the pixels are teeny-tiny and thus sometimes struggle with adhesion. Make sure your bed is level and clean!
Update: Added an openScad file to create a custom sized pixel board
