Several months ago I ordered a small laser engraver from an online auction for a project, and it died after a short time. When BangGood.com gave me the chance to pick out some free merchandise, I jumped at the chance to try some of their laser components. Thanks to some new parts I was able to get this machine working again. I also got out in the shop to make some new acrylic mounting plates, and designed and 3D-printed a new add-on for the laser.
