This is a model of a motorcycle tire ashtray. The upper diameter is about 10cm, and the height is about 4cm. I can change the diameters and make changes to the design. I will upload pictures of the printed model.Update: There is a second model which I like more. The dimensions are the same but the holes are more tight and has a better fit. 2nd model is the light colored one and is called Part2. Both models are included in the package.
