An adaptation of Matt3ry's Shield Draciel for the Burst System.

To assemble it you will need:
-2x Metal Balls (I used some bijou small balls)
-1x Spring (It pushes the Burst System's Lock

-3x Small nails with a round-head (2x to hold the base and 1 for the Metal Tip)

You could also use super glue instead of the pair of nails, but It won't be strong enough for some matches.
I personally used PLA for this print and it didn't break after many battles.
