Neje Master Adjustable Module Holder

All credit goes to Nicky Norton (Norton white tile method) for the idea for aligning laser beam to the thinnest
Scan angle
Designed by me for the Neje master laser engravers with a 30mm x 30mm laser diode casing. Mounting holes are 16.5mm apart(so may work with Ortur modules are also the same size I think?)

Depending on the way your laser module was installed in its housing you will probably find that the beam is on an angle to the scan line.

Installing this will allow you to turn the laser module and align it correctly to the scan line path producing much better quality in your engraving.
Finally refocus your laser and enjoy better results!
