Hi!!
I've designed this pretty cool saiyan scouter that you can download and 3d print and play around a bit with it, I used a green kitchen detergent bottle to do the visor and i think it looks pretty cool!!
It was a fun build and it took me just a few hours!!
for the "holographics' i used a yellow print label, you can also pay around with the designs and if you want to do it right you can cut it exactly the same as the one in the anime using a laser engraver.
Have fun!!!
