About this 3D model

This is a small golf ball model that I made to hide the knot on an elastic rope so I can tie a golf ball holder on my bag. I've been calling it a "Tether" but a "Knot Bead" might be the correct term? I added a .3mf file where I scaled the diameter of the ball from the size of a regular golf ball to 25mm. This also makes it so the 3mm elastic rope I used is a nice snug fit when you tie a knot on the end.
