Hardwired AAA batteries
thingiverse
Convert your AAA battery draining LED lights to a hard-wired 4.5V source! To complete the project you'll need: - Number 4 button head screw (positive terminal) - Number 6-32 x 3/8 Knurled Head Screw (negative terminal) - 4.5V AC to DC converter - DC plugs: I used 3.5x1.35mm power cables (both male and female) - Speaker wire to solder power cables to - Heat shrink and heat gun to properly isolate solder joints. Also included is a mounting bracket I created to hang each light from the wall. You may need to design your own for the brand/shape you've purchased. I recommend using a brim adhesion to help stabilize the narrow print, but it may not be required for your printer.
