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. Post-Printing Assembly: After printing I cleaned out holes with appropriate drill sizes Parts: QTY 1: gear QTY 1: https://www.kjmagnetics.com/proddetail.asp?prod=MM-D-12 QTY 1: 10mm M3 shcs QTY 1: M3 washer.
