Recently I created a 3D printed “target” holder to help with 2nd laser mirror alignment.  This is a much improved “jig”, that now allows to align both mirrors.

So what’s new?

First of all, I made modifications to 2nd mirror alignment jig. It was constantly falling off, so I added handles on the sides, so now you can use simple rubber band to hold it in place. I also added small eyelet on top for easier storage when not in use.

Biggest change was addition of 1st mirror calibration jig.


Please note that I placed it on the wrong end of the mount, only to take picture. It normally will go on the other end.

And finally, I created simple “cross-hair” templates to be used with these 2 jigs.  You can print them out and cut out with scissors or use your laser cutter, to etch image and cut out shapes. You’ll need to use at lest some heavy card-stock or mat board.


File designs and templates are available at Thingiverse.

As always keep in mind these will only fit Shenhui Laser SH-G350, and that I cannot be sure of, as they might include different mounts.

Update: If you don’t have a 3D printer, I can print these for you! Check it out in my online store! 🙂
