12mm foam wheel landing gear parts, including two 12mm wheels, a 0.5mm steel wire landing gear, and a little heat shrink tube

Parameter

The wheels have a concave surface on one side and a smooth side on the other

Install the wheels with the smooth side facing inward

The concave side is facing outward

Originally, the manufacturer's design was to bend the main wheel of the wire card with needle-nose pliers, and there was no plastic parts that were easy to jam the 0.5mm steel wire, and then I thought of the 0.6mm heat shrinkable tube, which can be fixed with the heat shrinkable tube, and pay attention not to break the wheel when heating!!

A complete set weighs 0.24g, and a single wheel weighs about 0.06g
