window hook
thingiverse
I'm part of a bigger universal holder system now. I couldn't find these parts anymore, so I decided to replicate the piece I had on hand. It's used inside windows to hold things like lights in place. I made this using both PLA and PETG without any issues. In the photo you see the original white PLA one, and the black PETG version side by side. Since it prints flat against the bed, no supports were needed at all. I printed with a 0.2 layer height.
