3mm LED fob for ASSA key -flashlight

thingiverse

This keyless key is made of two parts that don't need any supports for printing and requires no soldering. The key itself acts as the anode, or positive side, so be mindful when bending its legs to fit a diode. Break-away tabs are included, which can be cut with a small knife or scalpel if needed. The key is securely held in place by a ring, so even if the fob breaks, it won't affect the key's function. This design uses a CR2032 cell battery, such as those found in IKEA's Plattboj remote controls.
