EDIT:

Please don't print the spinner base! it is giving many users issues.  Please find the new print profile on my page and print the one that has a negative extrusion.  This will fix the problem with the spinner not spinning properly.  Sorry and thank you for all the feedback. 

2-4 players.

Start by balancing the base in the designated stand or don't use the stand for a bigger challenge.

Rock paper scissors for who goes first or flip a coin. Whatever method is easier for you.

Spin the spinner and see what part you land on.

Stack the part on the triangles in any orientation.

If a part falls you lose.

Print in many colors to make it more fun or in a single color (2 plates in total, 4 if you choose to print the box).

The box is VERY close to the max the print bed can support. Make sure your filament is dialed in and dried for best results.
