Summary
Refrigerator magnet learning gear toy I made for my niece and nephew. Each gear has the # of teeth printed on them and a marker for one tooth, this allows teaching division ratios and basic counting.
After printing the orange gears I realized the necessity of having a handle to grab and spin. It has been edited on in the stl file.
The chamfers on the bottom are two fold. For one, it is easier for little fingers to pull gears off the fridge and for two it makes a nice round circle for your first layer.

Hello! I'm a STEM teacher and I want to make a magnetic gear wall for my students! I found your beautiful design and I was hoping this might be an option. I'm having trouble figuring out exactly what pieces would be needed from kjmagnetics. The link didn't work and I tried searching 10mm M3 but no luck. Can you help?
