Lightweighting with Wheel Cutting! Wheel Slicer Lightweight Processing Jig Tool for Mini 4WD (Wheel Width Approximately 9.1mm, Tire Width Approximately 8.1mm) This item is the perfect part for customizing your Mini 4WD. It's a wheel slicer, a jig for lightweight processing of Mini 4WD wheels. By lightweighting the wheels, you can achieve a lighter weight than usual. The wheel width after cutting is approximately 9.1mm (with some variation). (The tire width will be approximately 8.1mm.) Suitable for wheels with diameters of approximately 25mm, 23.5mm, and 20mm. If the wheel is loose when setting it, there is a slit in the center of the main body, allowing you to sandwich and secure the wheel. In that case, you can use a 30mm long screw for Mini 4WD to secure it. If it's still loose during processing, wrap masking tape around the wheel before processing. (Tightening too much may damage the wheel.) This listing is for the jig body only. (Wheels, fixing screws, etc. are not included.) The usage is very simple; please purchase only if you understand how to use it. This product is manufactured using a 3D printer. There are no issues with its intended use, but for improvements, the color and shape may differ slightly from the images. Please understand.
