These are parts for attaching different wheels to the Tamiya 1/12 scale radio-controlled models 'Porsche 959 Paris-Dakar Rally' and 'Celica Gr.B Rally Special'. They are used by fitting them onto the original hubs. These are made using a layered 3D printer. The material is PLA+, and the layer thickness is 0.15mm. Some adjustments, such as removing burrs, may be necessary. Packaging will be "bubble wrap + envelope". Thank you.
