Maybe the tiniest Thingivers thing? A pin thats snaps in the Ikea Skadis PegBoard elips hole. I notices that some hooks came loos if i took something from the board. This little pin fixed that. Maybe you have another use for it.
I love tinkering my designs together in Fusion 360. Mostly inspired by things witch have some use. I'm always open for new ideas. If it's within my skills to make it, I'm happy to have a go with it.
Have fun making!
