A rainbow-themed jump rope handle with a screw-on cap.

Print:

Although there are seven different colors here
The trick is to replace the material roll in the AMS when the printer moves to the next color. I mapped the six colors to four AMS slots and took a screenshot of the process:



During the printing process, when the printer finished printing the purple ink roll and retracted it, I replaced it with a green one.
When the blue material was being rewound, I replaced it with yellow. The screenshots helped me understand which parts needed to be replaced.

If you don't want to switch the consumables manually, you can print them.5 colorsVersion

Assembly:
Pass the rope through the lid and tie a knot, then tighten the lid.

This configuration is based on a model from Thingiverse:https://www.thingiverse.com/thing:3391222
I enlarged it a bit
