I had this idea when I saw the Streamlight MicroStream because I wanted a slim, minimally protruding light for my Atlas S-one handguard. I searched the web only to find no public designs and one cheeky twat selling an SLS printed mount for 30 bucks. So I designed these in fusion for myself and anyone else who wants it.

Update July 2024 - I just added the "Updated" version file, this simpler design is both stronger and lower profile while using less hardware and less supports than the original design. The only hardware required for this new mount is two standard M-LOK T nuts and two M4 x 14mm screws. (you can get away with screws as short as 12mm)

You will need to bend this Fairly with a lot of force to get the light in place, PLA+ should be able to withstand this. I have not tried other filaments but a stiffer TPU might do a good job in this application.

Print these in their as downloaded orientation with supports, use support blockers on the screw holes. (for the old "V2" version, also use support blockers on the clamping nut slots)

Older "V2" design - Requires 2x M2x12mm socket head cap screws and nuts, and of course the standard M-LOK screws and T-nuts. you may need to use longer or shorter screws depending on the application.
