Classic Tetrominos (Tetris forms)
thingiverse
As I couldn't locate any standard Tetrominos on Thingiverse, I've created them myself. You can download the *.stl files or the raw Freecad Files - please feel free to copy, adjust the size, remix, print, sell, or do whatever you'd like with them. I printed these using a 6mm height and 6mm width for each cube itself, so don't hesitate to resize as needed.
