Ratchet Fidget Thing

One day it came into my mind and then i just modeled it and printed it. It even worked perfectly the first try! To assemble just press the octopus looking part on the other part while also turning it slightly counterclockwise. The cylinder in the middle has a clearance of 0.1mm. Print both parts separate/do not print in place because they will fuse together! I have printed it using a 0.2mm nozzle but it should work with a 0.4mm one as well (might want to adjust the fuzzy skin though)
