This is a glasses holder with a ring installed on the upper part of the tray on the left side of the steering wheel. The ring is pressed against the panel and can also be used to hold parking tickets, etc. Several people were given prototypes to test, and the size was made larger because sunglasses are often bulky. The ring material is ABS without glass fiber, but contact with the lenses is a concern, so please take precautions when using it. The materials are a mount (ASA) and a ring (ABS), both of which are strong and heat-resistant. Regarding installation, the deformation of hooking the central tabs onto the panel is different from the creator, who knows the strength and bending properties, and it seems difficult to understand the amount of force needed at first glance. Several people were given a monitor test, and they seemed slightly confused, so the following installation instructions are also provided. It is easier to install with the ring attached. After firmly inserting the lower round part into the recess, Push down slightly towards the panel side and insert the central tabs into the gap in the panel and pull up. The direction and amount of force for this bending deformation are difficult to understand, but Please watch the installation YouTube short video via the QR code. Please consider purchasing this product with the understanding that it is a design by an individual and a 3D printed product using the FMD method.
