Interesting. I have those same glue sticks around the house... somewhere. Tracking it down will be a good task for my daughter.
I'd like to print directly on the glass as the heat bed is just so pretty that it should be displayed instead of covered in tape. Also, I'm a cheap skate. I'll have to try some of these.
I have a sharp but thick putty knife type tool that has been doing great getting things off the painter's tape. So far that hasn't been a challenge.
