I have noticed most people prefer to buy the IKEA Samla box to store filament. I found the Jysk Probox one to be much more to my liking.

However, as you might notice it only comes with 2 clips (which secure it pretty well in my opinion), even though the box has 2 more places where you can install clips, on the long sides.

So, I designed this clip that attaches to the “hinges” that the box has and rotates the same way as the original clips. 

My box is the 32L one, but I am pretty confident all sizes use the same height lid and clips. 

Feel free to give it a try and share your opinion!
