You can never have enough filament clips right? I see them pop up on Thingiverse and just grab them, they’re tiny and don’t take long to print and they’re useful. Here’s two different ones…
I needed some kind of a hook for my shelves and found these over on Thingiverse. I needed a lot of them so I figured I’d print one in each color of PLA filament I have.
These are nice and sturdy, but you need to print them with 100% infill to make them solid to make sure they can hold weight. These are the best ones I’ve come across so far.
