These will be launched on November 11th in Hemet California, but they are available now 🙂
To align the GlowForge C02 Lazzzer tube when you need to remove/swap/repair/replace your Glowforge tube.
I have the shims also: GlowForge Shims
Details of the SVG score file to get best results will follow.
You use the shim(s) to move up/down and the elongated slots to move left/right.
They come in a set of five. Laser head not included 🙂
