Storage box clamp (Regalux)

I had bought this plastic box to use as a dry box for my filament. When I picked it up in the store, there were some clamps from the same brand right next to it, so I bought a set of them too. Unfortunately they didn't fit very well and had no chance of keeping the box air tight.

So I made my own, beefier and tighter clips.
