This is a simple 2x2 gridfinity bit that is perfect for storing and organizing resistors. It has 10 slots for different values of resistors. There is a separate, optional tab that can be printed to add a label to the organizer. The open space in at the bottom side allows for easy retrieval of the resistors, and there is plenty of clearance to all allow for rolls of resistors to be stored without being removed from the adhesive strips.
