reel for filament samples that fits tall cans of soda or red bull

I build a 3d printer for a friend of mine and I wanted to send him a few samples of filament for his 1st prints.

During some other conversation he mentioned that they didn't have the edition versions of redbull and has never tried it.

So I had the idea since I was already making some reel for samples, I changed the middle hole to fit a red bull can.
