Adjustable mount for laser module

thingiverse

This device holds a laser module, positioned at a specific angle. I utilize two of these mounted on opposite sides of my 3D printer for leveling the build platform. First, I direct both lasers towards the platform's corner, resulting in a single dot. Then, I move the platform and ensure only one dot is visible if it's level. To assemble, thread the small holes with a 3mm tap, insert the laser module, attach main body to secondary body, place truncated sphere inside, tighten cradle with an M3 bolt, and secure main body on a surface using two M3 bolts.
