A silly idea that turned out well! Most flex PCBs are cut by laser, not milled, so you can make perforations by adding incomplete edge cuts. These disks are for cleanly joining LED strips at different angles and different radii, and they break apart with just my fingers, no other tools.

You can tear them at angles of 90°, 60°, 45°, 30°, 22.5°, 15°, or combinations thereof. (....ignore the Jokerman silkscreen, it's fine don't worry about it)
