This is NOT a model of mine, i took it from https://www.printables.com/model/692122-chopstick-fingers/files and generated a print profile for Bambulab P1S since the original 3mf was not compatible.
This tool is really useful for those people that are not comfortable using chopsticks for sushi and other oriental food :)
Eat your sushi like a pro!
P.S. i printed it with support (standard) although the slicer did not require it to give more quality to the finger caps, you might try without or with tree support (the standard was a bit tricky to be removed from inside the caps)
