Original plastic ring is made of expletive-infused plastic and of poor quality.
This is a replacement part designed from scratch, designed with more plastic material, and should last a lifetime. Made to fit grand katana - total destroy blender, it might fit some other cecotec blenders too.
Print this in PETG with 100% infill to fix your blender.
Be careful when driving in screws - do it manually and be careful not to overtighten them (it will break the part)
