This is an inner box for the Tamiya Mini 4WD Compact Bag. The color is black. The compact bag is a great size for events, but it can be difficult to take cars, parts, and tools in and out, so I made this. The product includes the three boxes shown in the second photo (inner dimensions approximately 18 x 11 cm, depths approximately 5 cm, 3 cm, and 2 cm). Please prepare the bag separately. The boxes fit perfectly in the compact bag when stacked in three layers. The boxes can be stacked in any order. The bottom box can be opened with a single action. I felt that a simple tray shape was more convenient than having dedicated spaces for motors and batteries. This allows for flexible storage. The third and fourth photos show examples of actual use and how the bag is stored. Please refer to them. Made with a 3D printer, the material is impact-resistant PETG. This is a personal creation, so please understand that there may be some burrs or surface roughness. Please understand that the product is non-returnable, non-refundable, and non-exchangeable.
