Weaken adhesive for opening a cell phone (like your picture)
Revive a Nexus 5X long enough to patch it and transfer the data off of it (a really frustrating process BTW)
Heat treat resin prints (place print in box, set box on bed, set bed to 80C, come back in an hour, turn bed off, wait for it to hit ambient, remove box) this process is great for hollowed prints as not only will it cause and trapped alcohol to evaporate out but it will further cure the part and increase the durability of the part as well (CNC Kitchen has a great vid on it)
Keep my coffee warm while I was building and setting up a NAS for a friend
