FlashForge Dreamer Lid Spacer
Using 4 of these lid spacers on the 4 corners below the lid will create a 7 mm air gap between the lid and the Dreamer's main body. This helps prevent heat build-up inside the Dreamer. This is useful when you want to keep dust off your print but also want to cool down your print environment.
The lid spacers are designed to be printed with ABS. They simply snap into place over the existing corner lid guides.
Note that I have an older FlashForge Dreamer with the foggy door. These fit my model perfectly. I don't know if they fit the newer Dreamer's with the clear door or not.
