Summary:
Just a wavy 26.8 degree cone with a handle. 26.8 was chosen as it's exact angle of Deep 27 as one of the creators mentioned in interview (do not ask me where, I read that on Reddit or YT). Wavy pattern was chosen it as gives better shaping abilities. I attached .step file if that helps you anyhow.
Usage:
Insert filter to deep 27, use sprayer to make paper a bit wet, twist negotiator inside.
Printing:
Model is already in print orientation, I used Navy Blue Extrudr PCTG as it's FDA approved but feel free to use whatever suits your safety concerns. To me there's no real way of making stuff food safe but this model doesn't really contact with food.
The author marked this model as their own original creation.
