Sometimes we just have to over-engineer to create a solution for a problem you didn't know existed prior to 3D printing :-).
Wanting to repurpose the sh***y little plastic bins one purchases from a multitude of "less than high quality" retail outlets, I designed this little pair of gems so I can hang those same plastic bins on my peg board.
I printed both left and right so they would print nicely without a bunch of standoffs.
These area good snug fit and designed to work with 1/4" pegboard. I have no idea how they will perform on 1/8". You're on your own there but do let me know.
