Rotor Key Ring
thingiverse
A snapshot from days of yore caught my attention - an image of a weathered (likely centuries-old) brass key ring featuring spinning discs to secure keys. The notion lingered at the periphery of my mind for an extended period before crystallizing, ultimately resulting in this creation after some trial and error. I opted for 3mm plywood, yet something more substantial would be advantageous if desired.
