Print a copy of side A and a copy of side B. Build the puzzle standing up, and the two sides will support each other.

This is a nifty 3_d jigsaw puzzle, one you can build vertically, where the pieces are cut on a bias so the left half helps keep the right half in place.

In the OpenSCAD file, there's a boolean value, sideA that you can switch between true and false to get the two versions.

It takes OpenSCAD about 20 minutes to render each side.
