Stack a tall tower of spools on the precarious baseplate before it collapses. 

Start with a empty build plate and take turns placing down a spool. If the tower collapses, you lose.

For printing, you can use the default values: 0.2 layer height. I added a more solid spool that prints a bit faster. 

You can use a layer height modifier after 5 mm on the build plate piece, from 0.2 layer height to 0.12 layer height, to make the bump rounder.

You will need about 9 spools per player (18 in total) to play the game.

I made a holder so you can store the game properly.

Have fun!
