A simple Riser for lifting up your ACE PRO. very useful for Dual ACE PRO setups as it lifts up the ace just high enough to be able to open the lid when its placed behind another ACE PRO 

printable on the Kobra 3 itself can gets assembled using m5 or equivalent SAE nuts and bolts, and mounts to the bottom of the ACE PRO using the  4 holes on the bottom of the ace using self tapping screws. you can also add double sided tape on the lower lip of the bracket for extra support but its not required
