i made the x-over to cross from the hoonigan handbrake lever (https://www.thingiverse.com/thing:5707671) to the ps4 remote holder handbrake base (https://www.thingiverse.com/thing:4920427)

requires two springs for the base
elastic bands to hold the remote in place
and a 6mm pin also on stl file to hold lever in place
screws to hold base a mounting point
and some glue for the hoonigan lever

side note a 6mm hole will have to be drilled once you are happy with the position of the lever when the srings have been fitted to allow pin to pass through i may add this in at a later date once i am happy with how it fits and works
