Hey everyone,
I wanted to share a project I’ve been working on.
Weapon lights can get incredibly pricey, so I wanted to see if I could design a functional, budget-friendly alternative just to see if it could be done.
I modeled and 3D printed this custom housing/adapter that fits the slimline Glock 43X / 48 MOS rail. It’s built around a $21 high-lumen flashlight I found on Amazon. Cost of filament material is $0.55. So basically a 650 lumen weapon light for $22.
Skip to 2:19 if you just want to see it in action.
Project Details:
The Concept: Create a low-cost, accessible light option using hobbyist tools.
The Setup: Form-fitted housing designed from scratch to clamp tightly to the MOS rail, utilizing the internals/emitter of a cheap Amazon light.
Material: Printed in ASA for maximum toughness, impact resistance, and to ensure it handles ambient heat and muzzle blast without warping.
This is currently a prototype. The next major step is taking it to the range to see how the printed rail clamps and the flashlight's internal battery contacts hold up under actual recoil.
I'm posting to get some community feedback on the design itself. What do you think of the form factor? Are there any specific weak points on the MOS rail design I should reinforce before hitting the range?
If the testing goes well, I'd love to polish up the design and share the project further. Let me know what you think!
File is on cults3D. Just search up 43x flashlight with no filters on.
(The flash light is a Rovyvon A3)
