Octolight - cheap zoomable flashlight for Octoprint

thingiverse

This is an adjustable LED flashlight designed for use with Octoprint and other timelapse solutions. Those flashlights are widely available online under various brand names. Searching for waterproof zoomable flashlights that run on 3 AAA batteries will typically yield results priced at around $5 per unit. You can power this device directly from the batteries, but I chose to drill a hole in the casing and thread two wires through it. These wires were then soldered to the empty battery holder, and an affordable adjustable buck converter was used to set the voltage to approximately 4 volts. This allows the flashlight to run directly off my Ender 5 power supply. This design is specifically tailored for use with the Ender 5 printer, but it should also be compatible with other printers that have a similar frame structure. For the diffuser, I repurposed an old cotton glove and held it in place using a rubber band. Another piece of the same cotton glove was wrapped around the rotating cylinder to provide added friction, allowing for smooth adjustment without any unwanted movement. This design utilizes OpenScad's thread library, courtesy of Cuiso, which eliminates the need to purchase a separate screw and nut. https://www.thingiverse.com/thing:3131126
