Ohm's Law Circle Wheel

What is it? The Ohm's Law circle or wheel is a pedagogical tool. The purpose of the Ohm's Law circle is to provide an easy-to-understand visual representation of the mathematical relationships in Ohm's Law, making it easier to solve for one variable when the other two are known. 

Printing: All the clearances are pre-made in the model for a standard printing with layer height of 0.2mm. The fit might vary depending on the printer used, but is designed with glue-in in mind. It can also be printed for a tight press-fit if the coins scale is appropriately adjusted. There are keys in the coins to ensure the text appears straight. Some fine-cleaning and removal of print residue might be required depending on your setup.
