Game Boy Pocket Backlight Trimmer Holder

thingiverse

I've never seen a Game Boy Pocket backlight dimmer installed this way, so I'm happy to share it with you in case anyone wants to try it! When deciding how to do this, I had three main criteria: 1. I wanted the Game Boy to look 100% unmodified, so no knobs sticking out, etc. 2. I wanted to be able to adjust the brightness without a tool. I've seen people hide a trimpot in the hole for the battery door clip but you need a little screwdriver to get to it. 3. I didn't want anything glued to the back plastic with long wires that would make disassembly and reassembly more annoying. So I opted to install a hidden "thumbwheel" style trimpot (trimmer? potentiometer?) to the left of the batteries under the battery door. It's adjustable with a thumb and is glued to the mainboard so the back plastic can simply lift off if I need to get back inside the Game Boy. This STL is designed for a Bourns 3352 trimmer. (It could possibly be for the 3352T variant—I got mine on eBay, but I'm not 100% sure.) Be sure to use the version with the leads going straight out the back, like in the included pictures. I used a 1K ohm trimmer but something like a 500 ohm might be better. (My screen goes completely dark after turning the trimmer only halfway.) I've included two STL's: The first is the actual STL I used that is currently glued inside my Game Boy Pocket, and the second should support the trimmer a little better and give you more surface area for the glue to hold.
