Mini Laser Engraver Upgrade Parts

These are the 3D printed part designs that go with my Instructable, [Making Your Mini Laser Engraver Safer And Better](http://www.instructables.com/id/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](https://youtu.be/C
