Calling all Star Wars fans and DIY enthusiasts! This DAMIENSABER Xenopixel 3.0 kit lets you build the most epic custom light saber ever. The inner core is 25mm diameter and 170mm long (so make sure your hilt is at least 25.5mm). The upgraded Xenopixel 3.0 soundboard is insane - we're talking 34 different sound fonts with options to add even more, 12 blade modes, 8 light effects including rainbow, pulse, fire, and flash. Control everything through the app: adjust volume, pick colors, change sound fonts, tweak sensitivity - you name it. The motion control is super responsive for realistic combat effects like clash, drag, and lock-up. Built with a secure battery compartment and high-quality ABS shell, this thing is made for actual dueling (yes, you can battle your friends!). Perfect for upgrading an old saber or building something totally unique from scratch. Pro tip: charge it fully before first use - when the battery's low, it makes clicking sounds or won't turn on. Get ready to create the light saber of your dreams!
