My daughter asked me to print her a rainbow for the desk in her room. Here is the custom design that we came up with.

Each arc is a different size and named by their true colors ROYGBIV, but of course you can print then in any color that you would like. Just make sure you print one of each size(color).

The tolerances were kept really tight so that they would compression fit together in the clouds without needing any glue.

While each cloud is technically a mirror image, I prefer to print on glass beds so that one side is super smooth. Thus the Left and Right Cloud files.

I printed the clouds on their side with "tree supports".

Arcs are 15% infill and Clouds 5% infill.

Please enjoy the rainbow!!!
