This is a simple, yet very useful design for a all-in-one spotlight. After scouring the internet for simple LED spotlight designs we could use to show off Lego models with simple and easy accessible materials, I came up with nothing.
I created this design to make it easy change the angle of the light and easy to change out batteries and bulbs. It uses very little filament and assembles in a snap. The battery carriage holds 1 3V CR2032 and the bulb is a 3mm or 5mm LED. Note: if the legs are extra long, you may need to trim them down a bit.

The only item that needs support is the bulb holder. Print this with the arms on your baseplate and the "nut" top facing up.
