Math trainer (rotate for random tasks)

A maths trainer for the 4 basic arithmetic operations. Perfect for starting primary school. By turning it, new random tasks are created again and again. You can choose to rotate the wheel with the arithmetic operations freely (for advanced users) or with a detent (for beginners).I could imagine that it is also a funny drink game ;-) For example: Who has more correct solutions in one minute. Features:- Multicolour print without AMS- Simple print & simple assembly (Just push all the parts together)- Choice of freely rotating wheels or with detent- The number plates can be freely arranged. And they can also be removed again later. Used materials: I used PLA+ for the wheel / bushing with detent. It works very well. I have not tested it with other materials. Print settings:If you not use the print profiles:All parts can be print with 0,2mm layer height and standard settings. The 3 frame parts need little supports for the hexagon pins. Assembly: Step 1: Remove the small supports on the hexag
