Photo / Canvas Wall Hanger - No Supports

Here I have taken inspiration from how door latch chains work , and created it into a hanging system, creating the basic idea I then refined the design to still be interlocking but also print cleanly with no supports,

the idea is you screw the Green part to your wall, and then the yellow part to your wall art / frame / picture / canvas, you then interlock the two parts,

i plan to further revise the design as I see fit, and welcome your input on how you think this could be improved.
