Introducing my Fidget game.
It's a “print in place” model. The only thing required is to add the printed balls in the fidget before the print is completed. If you use my print profile, there is already a pause included at the right time to do that. I've also included the balls on the same plate but, if like me, you want the balls to be a different color, I propose to print them on a separate plate before printing the fidget.
To work properly, the trigger will need to be break loose by moving it slightly side to side from the rear of the fidget on place shown below.
Also, please look at my other from the same series, the 3 levels Marble labyrinthe here:
