1/24 scale wheels created using a 3D printer. The material is UV resin. Diameter: F: 17.5mm R: 18.5mm, designed to represent 15-inch/16-inch wheels. After purchase, please contact me via the transaction message with the following information: * Attachment method: Please choose from pin type (compatible with T company/H company) or cap type (compatible with F company/A company). * Enlargement/Reduction Output (Free Option): Please let me know if you would like this. * Layer Pitch Change (+500 yen): Normally output at 0.05mm, but can be output at 0.01mm. This improves the resolution of the output and eliminates the need to remove layer lines, which is recommended. * Multiple Purchases: We can accommodate multiple purchases if you let us know the desired quantity. While designed to fit the kits I have on hand, modifications such as enlarging the mounting holes or adjusting the offset may be necessary for installation. Please be aware of this beforehand. Due to the nature of the material, warping or shrinkage may occur depending on storage conditions. Regarding the molding color, it appears black in the image, but may be changed without notice due to material availability.
