What it does

Widens your flashlight beam for softer, more spread-out light
Adjustable fit, designed for Zhishunjia ZSJ-T29 but customizable
Perfect for camping: hang from a tent or branch for area lighting
3D printed tech accessory that solves the narrow-beam problem
OpenSCAD design, ready to print and use right out of the gate

Turn your narrow-beam LED flashlight into a wide-area lantern with this simple, adjustable diffuser. Whether you're camping, working in tight spaces, or just need softer light, this 3D printed tech accessory spreads the beam for better coverage.

The default dimensions fit the Zhishunjia ZSJ-T29 flashlight perfectly, but because it's built in OpenSCAD, you can tweak the sizing to match your own torch. Hang it from a tree branch or the top of your tent, and you've got instant ambient lighting for the whole campsite.

Designed by Yenya, this diffuser is straightforward and functional, no complicated assembly, just slip it on and go. Good news: it works perfectly for turning a focused beam into something way more usable.
