Works as designed. Perfect solution for storing filament.

Only reason it did not get 5 stars is to me, and this is just personal preference, you have to turn the handle counter-clockwise which seems odd to me. if you have another print where the mechanism is reversed, please let me know.

brother was heading to Japan and found this to hold his phone. What a clever idea.

Showed this to both my wife and mother and so far, I’ve printed 9 of them. I’m sure I’ll have to do more, since my mother has started handing them out to her friends

Simple, yet so functional.
