About this 3D model
Easy to print key ring. 2 .stl files are available. Indeed the clip-on balls are not quite the same Ø depending on the manufacturer. They oscillate between Ø15 and Ø16. For this there are 2 sizes so as not to break the branches according to the balls you find. There is another file that exists in my creations with 4 branches named: PLP BALL CAGE "D".
