MicroRAM-L16 is a compact, 3D-printable adjustable laser guide mount designed for sewing machines.

It is built around a 16 mm diameter laser pointer and uses a dual Hirth-style indexed joint system for secure pan and tilt adjustment. The tapered 36-tooth joints lock in 10° increments and are designed to resist vibration while still being easy to reposition.

The mount includes a removable adhesive base for mounting to the sewing machine without drilling, a reinforced articulating arm, a split compression-style laser clamp, and tool-free thumb screw options for quick adjustment.

Designed for PETG and standard metric hardware, the MicroRAM-L16 is intended to be compact, strong, easy to print, and easy to customize or remix.

For the Hirth teeth, I would not push speed hard. Those are the precision features that make the whole mount work
