Filament Clip

https://www.thingiverse.com/thing:2850586

I made a thing! And it's functional 3D printing! Most of the filament clips on Thingiverse attach to the spool. I have a lot of different filaments with different spool sizes so I wanted a clip that was universal. I liked the design of one clip that came with some filament I ordered so I whipped it up in Fusion 360. I like this design because it will apply to ALL my filaments. 

Here's what they look like printed.

And on the spool.

If you need a really simple 1.75mm filament clip, you can check it out on Thingiverse. I'm sure you could scale this to fit 3mm filament as well. Happy 3D printing!
