I made a pair of "Nutz" accessories, specifically designed for installation on the rear of your remote-controlled car. To make it easier to hang a key ring, I thoughtfully designed a ring-shaped structure.

When printing, a 100% fill density was used, and the layer height was set to 0.16mm. The finished product was printed in a flat manner as shown in the figure.

This work was entirely completed by me independently, with no involvement from others. If you download and try it, please feel free to let me know your usage experience and opinions at any time.
