Index Controller Battery Addon! (2 Versions)

Edit: I added the “Index Controller Home Button Extender” to the files. A few people on Discord asked about the part shown on my home button in the picture, so I figured why not just include it. You can use double-sided tape to attach it to the controller button. 🛠️ Why I Made This Since my Index controllers aren't the newest anymore, I noticed shorter battery life. Instead of using an external battery pack strapped to my wrists, I designed a compact battery add-on that attaches directly to the controllers. I made two versions: Variant 1: Uses replaceable 14500 batteries. Variant 2: Uses a fixed "1800mAh" LiPo battery (real capacity ~1100mAh). Both variations are attached to the controller using double-sided tape. 🖐 Comfort Notes The two variants differ in size: I have medium-sized hands (I'm 1.85m tall). Variant 2 is slimmer and more comfortable, it doesn’t press against the back of my hand. If unsure, print one side of each design and test the fit on your controller and hand. 🔋 Ba
