Uses 4x1 mm magnets. I super glued the magnets. The pins that connects two parts are very small, so when I connected the parts I used a dot of super glue per pin although it holds well on it's own, but it will brake if you want to separate the parts.
0.16mm layer height
3 walls
30% infill
Part 1 needs to be glued to the window frame.
