For those of you that might be experiencing temperatures right up against the threshold of print or no-print: as has been discussed before, the Glowforge can experience some temperature creep from the electronics within. When it sits idle with the lights, etc. on, the temperature can rise and if you are near the temperature thresholds it can cause a no-print/temp situation, or initiate a cooling pause sooner in the print due to increased coolant temps.
The hinges are pretty awesome on the forge, and they probably don’t have a ton of stress on them if you’re opening the lid the full 90 degrees up… This design props the lid open just a bit, which should let the heat escape, be a little bit quieter than a fully open lid, and provide support for the hinges.
While I don’t have any pictures of these in use (I thought I did, but I can’t find them?), they are super easy to use. The bottom has a foot that rests on the crumbtray. It goes up and sits over the material loading door. And finally, it has a notch on the top that the lid rests in. The SVG only has one; you can just create a copy in the UI and have a pair ready to go.
