I built a simple gantry for my flashlight to clamp on to. I use it on my lack tower table. It gives my flashlight the 2 degrees of freedom I to highlight anything inside.
Any flashlight with a 27mm thick handle works. I am using: https://www.harborfreight.com/220-lumen-rechargeable-flashlight-63932.html
I also used a M3 screw and a nylon hex nut but the hole can take anything up to a M4.
