Somebody asked me to print rainbow mace and here it is.
You can print your own with wood and silver filament maybe so it will look like in the render.

You can watch the video about it here:

I've used Eryone Silk Mini Rainbow PLA :
http://bit.ly/EryoneRainbowPLA (affiliate link, you pay nothing extra, I get some change).

In order to maintain smooth color change I've cut off 3 meters of filament, printed part 2, 3, 4, 5. Inserted the 3 meters filament piece the other way round and printed part 1(oriented it flat side down).

I've used Fusion 360 to design it - source file included so you can modify it easily.

BOM:
M6 threaded rod 515mm long and two nuts,
CA glue or 3D Gloop.

Use brim for long and thin parts(2,3,4), supports are needed for part no. 5.
