You all had questions, I now have answers! Comments from my last filament storage video mentioned using a hygrometer to measure humidity levels. So I picked up some smart hygrometers, and ran a series of experiments to see how well to dry boxes really work.

![I Engraved a 3D Sculpture INSIDE Glass β ComMarker Omni X UV Laser Review
*** Use code christopherhoff for 5% off your order! ***
The ComMarker Omni X is a fully enclosed UV laser engraver that works on metal, wood, acrylic, leather, stone, glass, and can even engrave 3D sculptures inside solid crystal blocks. In this review I put the 6W version through a full month of real-world testing, covering everything from internal glass engraving and metal oxidation colors to wood cutting and leather work. Ill also walk you through the LiDAR autofocus, dual lens system, ComMarker Studio software, and Lightburn compatibility, plus one hardware issue I ran into and how ComMarker handled it. If youre considering a UV laser and want to know if the Omni X justifies the price, this is the video for you.
