Modular cube toothpick shapes

I wanted to make various shapes from cubes, using toothpicks. These nine shapes are all the possible joint combinations. The toothpicks are held firmly in these joints.

Now you can play Tetris in real life!

Update: I've included an image of how to make a piece with angled slot for diagonals, by combining on the slicer two normal pieces, the second angled 45 degrees on x and z axis (actually, -45 on my slicer). The order of the rotations seems to matter, experiment and then move it a bit to make the (imaginary) toothpicks meet at the corner. I don't think much precision is necessary.
