These are the 3D printed part designs that go with my Instructable, Making Your Mini Laser Engraver Safer And Better. They are designed to be used with any of the SuperCarver-style "Laser Engraver Printer Cutter Carver DIY Engraving Machine" units commonly sold for between $80 and $150, and I have applied them to a 1000mW @ 405nm unit branded HTPOW. See the after and before photos above. Here is a video from the webcam I placed inside the engraver -- it is not sped-up; this is the actual engrave speed.   These machines have the potential to very quickly cause significant harm. I'm not an expert in the law, nor in laser safety; I'm just a maker who sees the potential, both good and bad, of these little engravers. You bear all responsibility for safe configuration and operation of your laser. I'm just describing what I did to my machine in an attempt to reduce the risk and improve functionality.

About the author:
ProfHankD
I'm a Professor of Electrical and Computer Engineering at the University of Kentucky, best known for things like having built the world's first Linux PC cluster supercomputer in 1994... although around the 3D-printing world I'm probably best known for my HingeBox (which Tested popularized). My research group (Aggregate.Org) really is about improving computing systems by making the various SW+HW components work better together, which we do for many different types of computer systems: supercomputers, digital cameras, ... and now 3D printers. I had some experience with tool and die making using Bridgeport Series I CNCs as far back as the late 1970s, but my 3D printing adventure started in late 2012 with purchase of a MakerGear M2 for my lab to make custom camera parts in support of computational photography research. I now use multiple MakerGear M2 and Wanhao I3 3D printers, several semiconductor laser cutters, a 3040T CNC mill, a programmable paper cutter, and a small vacuum forming machine.
