Guitel office chair castor

The castor is from the Guitel brand specifically for office chairs with a universal stem,
The repair was necessary for two reasons, because some of the wheels on my chair stopped turning and the appearance no longer looked as if it were new.
The 3D printed version of this product consists of several parts and their layers are oriented so that they do not break during use. Glue is required for assembly. I am attaching the assembly instructions, which also indicate where the glue should be applied. The wheels are made in two versions: all black and a black wheel with a gray edge to resemble the damaged original wheel. I have also added a simple technical drawing of the stem and a stp file, specifically the part by which the stem is anchored in the wheel, so that they can convert the stem to their chair if this part does not fit their chair.
