Glowforge Blast Gate Assembly

thingiverse

I recently encountered my first instance of humidity entering the GlowForge machine and warping a cardboard jig I had set up. To solve this issue, I decided to create a blast gate that could be easily installed directly into the machine's outlet port and then connected to the duct on the other side. This design would provide a super low profile and make installation easy. My blast gate is made from 1/8-inch acrylic, which should limit expansion caused by moisture and allow for smooth movement. It fits snugly over the outlet and can be secured to the duct with a clamp. Note: I designed this blast gate specifically for the GlowForge Plus model. It may work on the basic model as well, but it will need to be rotated to avoid obstructing the passthrough port on the pro model.
