I have edited the lever actuator from a different design it does work but I hate how it looks

Changes

    Increased Blade Cutout length inside of the front mount to prevent binding
    Created flat stop block on Blade Holder to prevent binding
    Created small chamfers on print bed side of blade holder to hopfully prevent having to be                filed down
    Increased Clearance in Lever arm for new Blade holder
v2.3 - Reinforced lever arm
v2.4 - Made lever arm thicker and made adjustment to the lever mount for the same fit
V2.5 - Created left and right variants of the fronts with accel attachments
