Alternating stripes of tape - one "sticky side up" piece of tape is held by two adjacent "sticky side down" pieces

Stripey kapton tape for glass beds

Some time ago I put a borosilicate glass bed on Squirty. I really like it because PLA will stick firmly to it when it is hot, but will pop off easily once it cools down. It is also really easy to clean. The only issue I had was how to attach it to the aluminium print bed surface. I know a lot of people use binder clips, but they have the disadvantage of slightly reducing the print area and also jut out above the print surface, risking collisions with the nozzle. Up until now my approach was to use kapton tape along the sides of the bed. It wasn’t a great solution because the glass still could slide back and forth slightly relative to the aluminium bed and it also tended to peel off over time. Today it occured to me that what I needed was double sided kapton tape. Such a thing does exist, but rather than ordering it I decided to cheat by alternating stripes of kapton tape with one “sticky side up” piece of tape stuck down by two “sticky side down” pieces. This arrangement holds the glass in place really firmly and yet I think I could still remove the bed without causing any damage.

This is a really simple idea that probably should have occurred to me years ago, but I am unreasonably pleased with it!
