This is a part used to replace a spare tire with a genuine tire, or to fill the hole when the spare tire is not in use. It supports four patterns with different combinations of parts (photos 2-5). The basic parts (two square-shaped pieces) have a direction. Both have notches on the "upper side." Reference video: youtu.be/aBAzqahCasQ Can be installed without modification. The shovel is designed to fit the one from a 100-yen shop (Seria). Please prepare it separately. The product is made by a layered 3D printer. The material is PLA+, and the layer thickness is 0.2mm. Fitting may be required. Packaging will be "bubble wrap + envelope." Thank you.
