3D printing working chain as one object, soft tires from scratch for 1/4 Scrambler Bike

Chain STL (suitable for simplest 3D printer). The chain is circular, It comes with a lock to be able to change the length. The chain I made is used for aesthetics, functional chain should have thicker parts and be printed with firmer material. 00:00 chain 03:30 tires 08:30 assembling
