Remix of a mathematical puzzle

This a nice puzzle as designed by lorenzo @lorenzo_540536 here in Printables.
The goal is to have the same total of the numbers on each and all the spokes. 
For example we could have on one spoke the sum 13+3+12= 28, on another: 6+20+2=28.
I liked the idea and how Lorenzo had implemented it.
It is great for children to learn addition.
 It is more difficult then Sudoko!

I printed it with 0.2 mm structural layer height and a color change to make the numbers visible.

To make it colourful I used white as base for all rings, but different top colours. In this way the numbers show white. Of course when you use black as base the numbers will then be black etc.
The 3mf files have the color change.

The screw is a standard M5 x 10 mm screw with an inside hex head. For the nut use a self locking one. You can also use Loctite to secure a standard nut. 
Other types of M5 fasteners should also work.

I added the Fusion 360 file. So you can make changes. If you like and printed, or you modified the design (like changing the numbers) please share the result here,
