Thinnest and sturdy chopstick holder

In my idea, it is not the chopstick holder that is printed, but the mould in which a piece of 1.75 filament is formed into the chopstick holder. 
The former should be printed from PETG, as heat is needed to shape the filament. I haven’t try it with PLA, maybe it works with that too.
This is a different way altogether and maybe only for craftsmen to copy.

The converted filament is surprisingly stable and can easily withstand heavy chopsticks Or other cutlery.

Work your way through bit by bit with the hairdryer or hot air gun. You can't mould it in one piece. Remember that PLA does not tolerate much heat. Less is more here. It may take a few tries to get it to work, but it's just filament leftovers, which everyone has. Therefore, it is not tragic if you make a few attempts.
Have fun, when you try it.

The hole for inserting the filament at the beginning is made for right and left handers.
