Just another best filament clip

I tried different variations of filament clips, like the one by Extrutim, MrMinion or in the style of the one by Renz Dani. 

Most of them had the risk of the filament end coming loose in my drawer. So i redesigned this one from scratch the way i needed it. 
It's pretty firm, so you may have to cut the filament end after unloading the filament. But trust me, this one won't come off in your drawer.

Apart from their outline, the round version and hex version are identical.
